Question

Write an app that reads an integer, then determines and displays whether the integer is odd or even. [Hint: Use the remainder operator. An even number is a multiple of 2. Any multiple of 2 leaves a remainder of 0 when divided by 2.]

Answer 1

Answer:

#include <stdio.h>// header file

int main() // main function definition

{

   int number; // variable declaration

   scanf("%d",&number); // user input for number

   if(number%2==0) // check the number to even.

   printf("Number is a even number"); // print the message for true value

   else

   printf("Number is a odd number"); // print the message for false value.

   return 0; // return statement.

}

Output:

• If the user inputs is 2 then the output is "Number is a even number".
• If the user inputs is 3 then the output is "Number is a odd number".

Explanation:

• The above program is to check the even and odd number.
• The first line of the program is used to include the header file which helps to understand the functions used in the program.
• Then there is the main function that starts the execution of the program.
• Then there is a variable declaration of number which is declared as an integer which takes the integer value because the program needs the integer only.
• Then the scanf function is used to take the inputs from the user.
• Then the if condition check that the number is divisible by 2 or not.
• If it is divisible print "even number" otherwise print "odd-number".
