C Program to Check Whether a Number is Even or Odd In this example, if...else statement is used to check whether a number entered by the user is even or odd. An even number is an integer that is exactly divisible by 2. Example: 0, 8, -24An odd number is an integer that is not exactly divisible by 2. Example: 1, 7, -11, 15 Example #1: Program to Check Even or Odd #include <stdio.h> int main() {     int number;     printf("Enter an integer: ");     scanf("%d", &number);     // True if the number is perfectly divisible by 2     if(number % 2 == 0)         printf("%d is even.", number);     else         printf("%d is odd.", number);     return 0; } Output Enter an integer: -7 -7 is odd. In the program, integer entered by the user is stored in variable  number . T...
