Basic calculator

#1

Kindly help me with this…My code does not pass all test cases

#2

Check the Output format for Invalid Operation case.

#3

Did that…still one of the test cases failed…

#4

You have taken input variables as unsigned long long int, so if their ans is negative after some operation you won’t get the desired ans.

#5

Okk…Got it…thanks…doubt resolved

what is wrong in my code can you tell please
only 1 test case got passed
#include
using namespace std;
int main()
{
long long int n,m;
char ch;
do
{ cin>>ch;
if(ch==‘X’ || ch==‘x’)
{break;}
switch(ch)
{
case ‘+’: {cin>>n>>m;
if(n<=100000000 && n>=0 && m>=0 && m<=100000000)
{cout<<n+m<<endl;} break;}
case ‘-’: {cin>>n>>m;if(n<=100000000 && n>=0 && m>=0 && m<=100000000)
{cout<<(n-m)<<endl;} break;}
case '’: {cin>>n>>m;
if(n<=100000000 && n>=0 && m>=0 && m<=100000000)
{cout<<nm<<endl;} break;}
case ‘/’: {cin>>n>>m;
if(n<=100000000 && n>=0 && m>0 && m<=100000000)
{cout<<(n/m)<<endl;}
break;}
case ‘%’: {cin>>n>>m;
if(n<=100000000 && n>=0 && m>0 && m<=100000000)
{cout<<(n%m);}
break;}
default :{cout<<“Invalid operation. Try again.”;
break;}
}
}while(1);
return 0; }
