There are many ways to determine wheter the number is odd or even. Here is two:
1. Check with modulus operator (%)
The modulus operator returns the remainder when dividing two numbers.
Even numbers doesn’t have a remainder, but Odd numbers have 1.
2. Check by bit operators

Here is the code:
1. With modulus operator (%)
———————————-
#include
int main() {
int number;
printf(“Input integer\n”);
scanf(“%d”,&number);
if(number % 2 == 0) {
printf(“Even\n”);
}
else {
printf(“Odd\n”);
}
return 0;
}
———————————-

2. Check by bit operator
———————————-
#include
int main() {
int number;
printf(“Input integer\n”);
scanf(“%d”,&number);
if(number & 1) {
printf(“Odd\n”);
}
else {
printf(“Even\n”);
}
return 0;
}
