C Program to Check if a given Integer is Odd or Even:

Problem Description

The program takes the given integer and checks whether the integer is odd or even.

Problem Solution

• Take the integer to be checked as input.

• Find the remainder of the integer by dividing it by 2.

•  Use if,else statement to check whether the remainder is equal to zero or not.

• Print the output and exit.

Program/Source Code

#include <stdio.h>
void main()
{
    int ival, remainder;
 
    printf("Enter an integer : ");
    scanf("%d", &ival);
    remainder = ival % 2;
 &nbs....

Program/Source Code

#include 
void main()
{
    int ival, remainder;
 
    printf("Enter an integer : ");
    scanf("%d", &ival);
    remainder = ival % 2;
    if (remainder == 0)
        printf("%d is an even integer\n", ival);
    else
        printf("%d is an odd integer\n", ival);
}

Program Explanation

• User must first enter the integer to be checked which is stored in the variable ival.

• Find the remainder of the integer by dividing the variable ival by integer 2 and the value is stored in the variable remainder.

• Use if,else statement to check whether the value of the variable remainder is equal to zero or not.

•  If it is equal to zero, then print the output as �??the integer is an even integer�?�.

•  If it is not equal to zero, then print the output as �??the integer is an odd integer�?�.
