Chapter 6, Problem 6.31E

Program Plan Intro

Program Plan:

• In the program, we include the header files as required.
• Function prototype will be declared.
• Declaring main() function as integer type.
• Taking the function gcd() as int type function to find the greatest common divisor number between two numbers.
• Variable declaration: gcd1 and gcd2 is aninteger type variable which will carry the user entered number from the main function to the gcd().
• Declaring the return_gcdas ainteger type which help to find the gcd number.
• num_1and num_2 are declared as integer type variables which takes input from the user in main() function.
• Calling the gcd() in the main().
• gcd() returns the greatest common divisor.
