Answer to Question #260657 in C for answer

Question

Write a C program that displays the following menu on the screen:

   MENU OF OPERATIONS

  By: <Your Name Here>

  [ 1 ] - Addition

  [ 2 ] - Subtraction

  [ 3 ] - Multiplication

  [ 4 ] - Division

  [ 5 ] - Modulo Division

  [ 6 ] - Quit

  Enter Your Choice:  3

  You have chosen Multiplication!

  Enter three integers: 89 78 67

  Sum = 465,114

  Thank you for using my program...

The user has to be prompted to input a number of his/her preferred operation and will then be asked to enter three integers and display the computed value based on the inputted operation.

#include <stdio.h>
#include <stdlib.h>


int main()

	int ch=-1;
	int number1;
	int number2;

	int product;
	double div;
	int modulo;


	while(ch!=6){

		}else{
			printf("Wrong menu item.\n\n");
		}
	}
	printf("\nThank you for using my program...\n");


	getchar();
	return 0;
