All the test cases not psses ? why

#1

#include
using namespace std;
int main() {
char ch;int a ,b;
do{
cin>>ch;
if(ch == ‘x’ or ch == ‘X’ )
exit(0);
if(ch == ‘+’ or ch == ‘-’ or ch == ‘’ or ch == ‘/’ or ch == ‘%’ )
{
cin>>a;
cin>>b;
}
switch(ch)
{
case ‘+’:cout<<a+b<<endl;
break;
case ‘-’:cout<<a-b<<endl;
break;
case '’:cout<<a*b<<endl;
break;
case ‘/’:{if (b!=0) cout<<a/b<<endl;}
break;
case ‘%’:{if (b!=0 ) cout<<a%b<<endl;}
break;
default:cout<<“Invalid operation .Try again”;
}
}while(ch!=‘x’ or ch!= ‘X’);
return 0;

Hello @amishakumari,

Missing end line operation.
Correction:
cout<<“Invalid operation .Try again”<<endl;

Hope, this would help.
Give a like if you are satisfied.

Hello @amishakumari,

Why have you posted one more doubt regarding the same?
You should have asked me if it wasn’t working.

Mistakes in your code:

  1. You are not following the costraints:
    0 <= Input integers <= 100000000
    ( It is assured that the second integer provided for division and modulo operations will not be 0. )
    a and b should be of type long

  2. Missing cout<<endl; in default case.

  3. You have written wrong output statement for default case:
    Required: Invalid operation. Try again.
    Yours: Invalid operation .Try again
    Problem:
    Position of fullstop ‘.’ and missing fullstop

  4. Wrong condition inside while

I have corrected your code:

Hope, this would help.
