C Program Print First N Prime Number using Recursion

By Dinesh Thakur

 In this program required variable are declared for functioning criteria. Then using loop statement for fulfilling the requirement of repeat the process. Then to use if condition to check whether the number is prime or not. After finding the prime number the next process is to elaborate them using while statement or if condition if number division able by declare value then break the statement else it will increase the value for variable and then if (y==x) then return the value as required.

Problem statement:-
This program is an implementation about to print first N prime number using recursion function.

  1. Declaring Variable as required.
  2. Using required function or statements.
  3. Display result on the screen.

This C program is successfully compiled and run on a System. Output is shown below. 

void main()
{
         int a[100],i,j,k,n,b;
         int prime(int);
         clrscr();
         printf("Enter no of elements : ");
         scanf("%d",&n);
         printf("Enter a no : ");
         for(i=0;i<n;i++)
             {                
                 scanf("%d",&a[i]);
             }
                for(i=0;i<n;i++)
                    {

C Program Write a Program to Print a Pascal Triangle

By Dinesh Thakur

In this program to Print the Pascal Triangle Two core concepts will be on the trot. The Control statement (if-else), and Loop Statements. There in the program Integer type Variables declare which use to contain the value. Here variable i,j and Num will use in the Loop statement as according the requirement. As required in the program Nested Loop used for fulfilling the condition along within the control Statement.

In the Program to print Triangle the loop Statement will be used many times like nested Loop Statement. As shown in The Program value entered in condition place and with the if condition used either condition gets true will be print desired row or else part will be followed to print in else condition the calculation will be manipulated for getting the correct output.
Problem Statement:-
Pascal Triangle Which we might have studied in Binomial Theorem here we Print Pascal Triangle. With the use of Loop Statement and Control statement. Write a program to read the data and determine the following:

  1. Entering the Number for Triangle.
  2. Using loop Statement.
  3. Using Control Statement for condition.
  4. Display output on the Screen.

In this program user ask to pass array to function. User declare the variables along with functions for process to pass array like void read (), void dis (). Arguments also declared within function to pass value. Array type variable contains the array elements within. User asks to enter the value as regarding. And then user call the function for passing value to array in a function user declares for loop for to print a value. The other function is been also call and loop statement also declare for another printing method. And display on the screen.

Problem statement:
This is C program that asks user to show how to pass a value on the array through function.

  1. Declaring the variables.
  2. Using functions.
  3. Using loop statements.
  4. Display result on the screen.

Here is C source code for passing array to function. Output of this program shown below. 

#include<stdio.h>

This is a C program where user asks to enter the value of matrix (order of matrix) and to find the transpose of matrix order. Means the rows will convert through columns what else the order of matrix. 

In the program variables are declared of Array type that will contain the value. User ask to enter value and the loop statement for verify the condition. The early loop statement will use to print a Matrix and the next one for finding the transpose of matrix. Nested loop statement is implemented in this program. And in the end to print the value on the screen.
Problem Statement:
This is C program to find the Transpose of matrix. User has to print a Matrix for transpose process.

  1. Declaring variable.
  2. Using loop statement.
  3. Printing result on the screen.

C Program Write a Program to Find the Greatest Between 3 Number

By Dinesh Thakur

Let us use variables a, b and c (all of type int) to represent three integer numbers and variable max (also of type int) to represent the maximum of them.

It first accepts the values of variables a, b and c. To determine the maximum number, the larger number of a and b is first assigned to max using the if-else statement. Then the larger of variables max and c, which is the maximum of the three given numbers, is determined using a simple if statement. Finally, the value of max is printed. The program is given below.  

void main()
{
       int a,b,c;
       clrscr();
       printf("Enter the Value of a = ");
       scanf("%d",&a);
       printf("Enter the Value of b = ");
       scanf("%d",&b);
       printf("Enter the Value of c = ");
       scanf("%d",&c);
       if (a>b&&a>c)
         {
                 printf("a is Greater ");
         }
      else if(b>a&&b>c)
              {
                   printf("b is Greater");
              }
      else
             {
                   printf("c is Greater");
             }
                   getch();
}

ASCII code means the character code that brings in a numeric form for every character so that computer can read the content because computer only understands the machine language or binary system. ASCII stands for (American standard code for information interchange). There are different type of ASCII code like for Capital characters ASCII code numeric value starts from 65 (A=65) or small characters like a starts from 97 (a=97).

In this program user need to check out the ASCII code for character for this user declare a variable name m1 that will be contain the value for ASCII code checking process. User uses control statement for checking the ASCII code. User asks to enter the value as character. if(m1>=65&&m1<=90) then the character value will be added with 32 to find out the ASCII value else the condition will be if(m1>=97&&m1<=122) then the value will be deducted from 32. And if not any condition lies true then message will be nothing for both character values.
Problem Statement:
This is C program to check out the ASCII code value for character.

  1. Declare the variables.
  2. Using control statements.
  3. Display result on the screen.

Here is C source code for Checking out the ASCII value for character. Output of this program shown below. 

#include<stdio.h> 
 void main() 
 { 
       char m1,m2; 
       clrscr(); 
       printf("Enter any Char : "); 
       scanf("%c",&m1); 
       if(m1>=65&&m1<=90) 
         { 
            m2=m1+32; 
            printf("m2 : %c",m2); 
         } 
      else if(m1>=97&&m1<=122) 
        { 
                   m2=m1-32; 
                   printf("m2 : %c",m2); 
        }

C Program Write a Program to Check the Char is Vowel or Not

By Dinesh Thakur

A given character is a vowel if it is one of the following characters: A, E, I, O and U. The switch case given below tests whether a given character is a vowel or not.

Note that we have to compare variable ch with uppercase as well as lowercase letters. We can reduce the number of comparisons in the above code if we first convert the given character to uppercase (or lowercase) representation. Thus, the condition in the switch involves comparison with uppercase (or lowercase) letters only. The code using this approach is given below. 

#include<stdio.h> 
 void main() 
 { 
          char a; 
          clrscr(); 
          printf("Enter any Alphabet : "); 
          scanf("%ch",&a); 
          switch (a) 
               { 
                   case'A': 
                   case'a': 
                   case'E': 
                   case'e': 
                   case'I': 
                   case'i': 
                   case'O': 
                   case'o': 
                   case'U': 
                   case'u': 
                                  printf("It is a Vowel"); 
                                  break; 
                   default: 
                                  printf("It is a Consonent"); 
 } 
                                  getch(); 
 } 
 Output : 
 Enter any Alphabet : i

C Program Demonstrate the Use of Goto Command

By Dinesh Thakur

This program asks user to define the Goto Command. Goto command is a skip through command in C like if any condition got terminated or false the Goto command skip the process to desired location where it sets for skipping.

User takes the demo about if-else condition for defining the condition. Like user declares the variable a and b and find out the greater from a and b. user put the condition if-else if (a>b) and puts a GOTO command that prints or skip to A else GOTO b and prints a message A is greater or B is greater which condition lying true.

Problem Statement:

This is C program that asks user to demonstrate the GOTO command.

  1. Declare the variables.
  2. Using go to command.
  3. Display result on the screen.

Here is C source code for demonstrate the Go to Command. Output of this program shown below. 

#include<stdio.h>
main()
{
int a,b;
clrscr();
printf("enter the value of a,b");
scanf("%d%d",&a,&b);
if(a>b)
goto A;
 else goto B;
 A:printf("a is greater");
  goto End;
B:printf("b is greater");
  End:
getch();
}
