C Program Copy One String to Another using Pointers
The program implements the Copy string to another string. The inner function “stcpy” takes 2 string pointers as arguments. “copystr” pointer type function declared and pointer type char variable declare. On next move the argument written “I am Dinesh Thakur” in the variable char pointer type and array type string variable. The required function used “cpystr”.
In the next move void copystr() and pointer type two variable dest ,src. While condition src!=0 then dstn=src then the string will be copied in dest then return the result as copied string.
Problem Statement:-
This program User asks to Copy String from one To another string with the Help of Pointer.
- Declare pointer type variable.
- Using While Statement.
- Display result on the screen.
This C program is successfully compiled and run on a System. Output is shown below
#include<stdio.h>
void copystr(char*,char*);
void main()
{
char*str1="I am Dinesh Thakur";
char str2[30];
clrscr();
copystr(str2,str1);
printf("\n %s",str2);
getch();
}
void copystr(char *dest,char *src)
{
while(*src!='\0')
*dest++=*src++;
*dest='\0';
return;
}
Output :
I am Dinesh Thakur
C Program Sort a List of Strings using Pointers
In this Program pointer concept is been used with the use of variables of pointer type char and integer type which contain the values. Reorder () also used for sorting the the string as required. In the program string is to be entered after that loop statement works. During loop statement the pointer type variable acquires the memory using malloc() function.
The next move is to sort the string here loop statement again come in use and then printing the string. So on the next step string functions comes into the frame like Strcmp() or Strcpy() for conditionally checks the string. Here while using the string function if condition also comes into the place for checking if the string sorted or not in the last the sorted string is to be displayed as output.
Problem Statement:
Here we have to make a Program to sort the String with using Pointer and string Functions.
- Entering the String.
- Using required functions.
- Using loop Statement.
- And Display The Output on the Screen.
The C program is successfully compiled. The program output is also shown below.
#include<stdio.h>
#include<conio.h>
#include<string.h>
void main()
{
char *x[20];
int i,n=0;

printf("Enter no. of String : ");
scanf("%d",&n);
printf("\n");
for(i=0;i<n;i++)
{
printf("Enter the Strings %d : ",i+1);
x[i]=(char *)malloc(20*sizeof(char));
scanf("%s",x[i]);
}
reorder(n,x);
printf("\nreorder list is : \n");
for(i=0;i<n;i++)
{
printf("%d %s\n",i+1,x[i]);

strcpy(x[i],t);
}
return;

C Program to Count Digits,White Space,Others
Let us use an array of characters (str) to store the string and variables nletter, ndigit, nspace and nother to count the letters, digits, white spaces and other characters, respectively.
The program given below first reads a string from the keyboard using the gets function and then uses a while loop to determine the desired counts. An if-else-if statement is used within the while loop to test the ith character and update the respective counter. Note the use of variable ch to minimize access to the array element (possibly improving its efficiency) as well as to improve the readability of the code. Finally, the program prints the counts.
/* Count letters, digits, whitespaces and other chars in a given string */
#include <stdio.h>
void main()
{
char str [81];
int nletter, ndigit, nspace, nother; /* char counts */
int i;
clrscr();
printf("Enter a line of text:\n");
gets(str);
/* count characters in string str */
nletter = ndigit = nspace = nother = 0; /* init counts */
i = 0;
while (str[i] != '\0')
{
char ch= str[i];
if (ch>= 'A' && ch<= 'Z' || ch>= 'a' && ch<= 'z')
nletter++;
else if (ch>= '0' && ch<= '9')
ndigit++;
else if (ch == ' ' || ch =='\n' || ch == '\t')
nspace++;
else nother++;
i++;
}
/* print counts */
printf("Letters: %d \tWhite spaces : %d", nletter, nspace);
printf(" Digits : %d \tOther chars : %d\n", ndigit, nother);
getch();

C Program Reverse the String using Recursion
This is C Program to Reverse the String using Recursion. In this Program user ask to reverse the string with the use of recursion function. Char type variable is a casual call for containing the value. In this program majorly the reverse function will come in use and some where the use of if condition too. The first instance program asks to put the line of text. Then after the reverse function and so on but in next move the if condition comes to check the condition for reversing the string if it’s take right then the reverse function will reverse the function and then display the reversed content on the screen.
Problem Statement:
This is the program that reverses the string using recursion function.
- Declaring the Function.
- Entering the line of text.
- Using if condition.
- Display result on the screen.
Here is source code of the C program that reverses the string using recursion function. The C program is successfully compiled. The program output is also shown below.
#include<stdio.h>
void main()
{
void reverse(void);
clrscr();
printf("\nEnter a Line of Text : ");
reverse();
getch();
}
void reverse(void)
{
char c;
if((c=getchar())!='\n')
{
reverse();
putchar(c);
return;
}
}
Output :
Enter a Line of Text : Hello Dinesh
hseniD olleH
C Program Trace a Matrix
This is C program where user asks to trace a matrix with giving the order of matrix and print it. Here user declares variables that are mandatory for storing the value with it. Some variables are array type to holding value multiple. User asks to enter the no. of rows and columns as order of matrix. And then enters a number then after user varies the loop statement for situation handling to print a matrix. Nested loop statements are used in this program to elaborate the condition itself for tracing the matrix. A printing message for the matrix elements. And then display matrix on the screen as a result.
Problem Statement:
This is C Program that ask user to trace a matrix.
- Declaring the variable.
- Using loop statement.
- Display result on the screen.
Here is C source code for tracing a Matrix. The output of this program shown below.
#include<stdio.h>
void main()
{
int i,j,a[10][10],m,n;
clrscr();
printf("Enter no: of Rows : ");
scanf("%d",&m);
printf("Enter no: of Columns : ");
scanf("%d",& n);
printf("Enter a Number : ");
for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
{
scanf("%d",&a[i][j]);
}
}
printf("\nElements are :\n");
for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
{
printf("%d ",a[i][j]);
}
printf("\n");
}
getch();
}
C Program Write a Program to Check No is +Ve ,-Ve, and Zero
void main()
{

if(a>0)
{
printf("a is Positive");
}
else if(a==0)
{

}
C Program Find the Greatest Between Four Number
#include<stdio.h>
main()
{
int a,b,c,d;
clrscr();
printf("Enter the Four Numbers :");
scanf("%d %d %d %d",&a,&b,&c,&d);
if(a>b)
{
if(a>c)
{
if(a>d)
{
printf("%d is big",a);
}
else
{
printf("%d is big",d);
}
}
}
else if(b>c)
{
if(b>d)
{
printf("%d is big",b);
}
else
{
printf("%d is big",d);
}
}
else if(c>d)
{
printf("%d is big",c);
}
else
{
printf("%d is big",d);
}
getch();
}
C Program Find The Leap Year
A year is leap if it is divisible by 4 but not by 100 or is divisible by 400. Thus, 1996, 2000 and 2004 are leap years but 1900, 2002 and 2100 are not. The program segment given below determines whether a given year (of type int) is leap or not.
#include<stdio.h>
#include<conio.h>
void main()
{
int year;
clrscr();
printf("Enter a Year : ");
scanf("%d",&year);
if(year%4==0&&year%100!=0||year%400==0)
{
printf("Leap Year");
}
else
{
printf("Not a Leap Year");
}
getch();
}
Output :
Enter a Year : 2013
Not a Leap Year
C Program Enter the Basic Salary and Find The Discount Against Salary
This is C program that asks user to find out the discount against salary. User declares the variables for storing the value in it. Here user asks to put the basic salary for finding out the discount against salary. For this procedure user declares the nested if-else condition. if(a==1000) then the discount will be 200 and if a=1500 then 500 and at the else condition no discount will be printing on the screen a s result as per. Here nested if-else condition comes into the lime light.
Problem Statement:
This is C program that asks user to find out the discount against the salary.
- Declaring the variables.
- Using if-else condition.
- Display result on the screen.
Here is C source code for calculate the discount against the salary. Output of this program shown below.
#include<stdio.h>
void main()
{
int a,discount;
clrscr();
printf("Enter Basic Salary :");
scanf("%d",&a);
if(a==1000)
{
discount=200;
printf("Discount : %d",discount);
}
else if(a==1500)
{
discount=500;
printf("Discount : %d",discount);
}
else if(a==2500)
{
discount=700;
printf("Discount : %d",discount);
}
else
{
printf("No Discount");
}
getch();
}
