I'm very new to C programming, and I need a help! I have made a program of calculator with the help of Switch Statement and I want this program to be in a loop, So that it ask the menu (i.e Enter your Choice: Divide,Multiplication,Addition etc) again and again with the user. Also I want, an End option with the Cases in Menu, which will close the program. I don't know how to code that End option which will make the Program Close. Please Help!
#include<stdio.h>
#include<conio.h>
int main()
{
int a,b,choice;
float sum,mul,div,sub,quo;
printf("\n\t\t\t\t CALCULATOR");
printf("\nEnter the First Number: ");
scanf("%d",&a);
printf("Enter the Second Number: ");
scanf("%d",&b);
printf("\n Enter Your Choice");
printf("\n\n1.Sum");
printf("\n2.Multiplication");
printf("\n3.Division");
printf("\n4.Subtraction");
printf("\n5.Quotient");
printf("\nYOUR CHOICE: ");
scanf("%d",&choice);
switch(choice)
{
case 1:
sum=a+b;
printf("Sum= %f\n",sum);
break;
case 2:
mul=a*b;
printf("Multiplication= %f\n",mul);
break;
case 3:
div=a/b;
printf("Division= %lf\n",div);
break;
case 4:
sub=a-b;
printf("Subtraction= %f\n",sub);
break;
case 5:
quo=a%b;
printf("Quotient= %f\n",quo);
break;
default:
printf("\n Unavailable Choice");
}
return 0;
getch();
