C Program to print all odd numbers

C Program to print all odd numbers from 1 to n by using for loop and if condition

#include <stdio.h>

void main()
{
    int i, n;
    printf("Enter value of n: ");
    scanf("%d", &n);
    for(i = 1; i <= n; i++)
    {
        if (i % 2 != 0)
            printf("%d\n", i);
    }
}
