#include<stdio.h>
void add();
void subtract();
int main()
{int choice;
printf("enter your choice:1.add 2.subtract:");
scanf("%d",&choice);
switch(choice)
{case 1:
add();
break;
default:
printf("wrong choice entered");
}
}
void add()
{int a,b;
char c;
do
{printf("enter two numbers:");
scanf("%d %d",&a,&b);
printf("%d\n",a+b);
printf("do you want to continue(y/n):");
scanf("%c",&c);
}while(c=='y'||c=='Y');
printf("\n");
}
why second scanf inside do while not working???
