Question

Write a program which gets user choice for addition, subtraction, multiplication and division with characters ’+’, ’-’, ’*’, and ’/’ respectively. This program should keep asking for two numbers and a choice to perform such operations inside a loop which can be only stopped by entering ’q’.

I've been working out of code blocks and now I'm not sure how to go about this

#include<iostream>

int main()

{

char oper;

int fno,sno;

while(1)

{

int res;

cout<<"enter operator \n";

cin>>oper;

if (oper=='q')

{

break;

}

else

{

cout<<"enter first number \n";

cin>>fno;

cout<<"enter second number \n";

cin>>sno;

switch(oper)

{

case '+':

res=fno+sno;

cin>>res;

break;

case '-':

res=fno-sno;

cin>>res;

break;

case '*':

res=fno*sno;

cin>>res;

break;

case '/':

res=fno/sno;

cin>>res;

break;

default:

cout<<"invalid operator \n";

break;

}

}

}
