Thread: Even & odd number

program with % operator

Code:

#include <stdio.h>

int main(void)
{
    int number;


    printf("Enter an integer: ");
    scanf("%d", &number);


    if(number % 2 == 0)
        printf("Even number is %d.", number);
    else
        printf("Odd number is%d.", number);


    return 0;
}

Enter an integer: 11
Odd number is 11.

Program with division operator

Code:

#include <stdio.h>
int main(void)
{
    int number;


    printf("Enter an integer: ");
    scanf("%d", &number);


    if(number / 2 == 0)
        printf("Even number is %d.", number);
    else
        printf("Odd number is %d.", number);


    return 0;
}

Enter an integer: 11
Odd number is 11.

Both program's give same output but they use different operator.

Which one programs is better and why this one is better

Actually, that is the point, and I think Greaper knows that. If int gave a remainder, then number/2*2 == number would always be true, which is less than useful.
