C Program Count Number of odd and even digits in a given integer number

by Dinesh Thakur Category: Control Structures

This program segment given below uses a straight-forward approach to count the number of odd and even digits in a given integer number(num).

Add numbers until a negative or zero is encountered

by Dinesh Thakur Category: Control Structures

The program segment given below accepts numbers from the keyboard until we enter a zero or a negative number and calculates their sum excluding the last number.

C Program Print Odd Numbers in a given range m to n

by Dinesh Thakur Category: Control Structures

In this example, a for loop is set up with values of loop variable num from m to n. The if statement is executed for each value of num and if nums an odd number (num%2 equals 1), it is printed using the printf statement. The output of this code is given below for m= 20 and n=40.

C Program Prints Prime Numbers in a given range m to n

by Dinesh Thakur Category: Control Structures

The outer for loop is set up to process each number in the given range. Each number is tested within this loop using the simplified code. The execution of the break statement causes inner for loop to terminate as it is the nearest loop enclosing the break statement. If the inner for loop is completely executed, i. e., if condition d == num is true, num is printed as a prime number.

C Program Print a comma-separated list of numbers from 1 to 10

by Dinesh Thakur Category: Control Structures

The if statement within the body of the for loop is used to print a comma after each value of the loop variable except the last one.

Consider the code given below to print a comma-separated list of numbers from 1 to 10:

C Program Print Pythagorean triplets

by Dinesh Thakur Category: Control Structures

Three positive integer numbers a, band c, such that a<b<c form a Pythagorean triplet if c2= a2 +b2 , i. e,, a, b and c form the sides of a right-angled triangle. To select the values of a and b such that a < b and a, b < max, we can use nested for loops as shown below:

C Program Sum of Digits of a Given Integer Number with do-while loop

by Dinesh Thakur Category: Control Structures

A program to determine the sum of digits of a given non-negative integer number using a while loop is presented in Program. The program segment given below does the same thing using a do...while loop.

C Program Date is Valid or Not

by Dinesh Thakur Category: Control Structures

Let us use variables dd,mm and yy (all of type int)to represent the day, month and year in a given date. The given date is valid only if year (yy)is non-zero, month (mm)is in the range 1 to 12 and day of month (dd) is in the range 1 to mdays, the number of days in a given month mm. An algorithm to determine the validity of a given date is given below.

C Program Prime factors of a given number

by Dinesh Thakur Category: Control Structures

As the name indicates, the prime factors of a given number are its factors that are also prime numbers, e.g., prime factors of 30 are 2, 3 and 5 but not 1, 6, 10, 15 and 30. One or more prime factors of a given number may repeat, e. g., prime factors of 120 are 2, 2, 2, 3 and 5.

C Program for GCD using Euclid’s algorithm

by Dinesh Thakur Category: Control Structures

Let us use variables m and n to represent two integer numbers and variable r to represent the remainder of their division, i. e., r = m % n. Euclid's algorithm to determine the GCD of two numbers m and n is given below and its action is illustrated form= 50 and n = 35.
