i am not able to understand whast wrong in
this solution
#include
using namespace std;
int main() {
char ch;
int N1, N2, ans;
do{
cin>>ch;
cin>>N1;
cin>>N2;
if(ch==’’){
ans=N1N2;
cout<<ans<<endl;
}
else if(ch==’-’){
ans=N1-N2;
cout<<ans<<endl;
}
else if(ch==’+’){
ans=N1+N2;
cout<<ans<<endl;
}
else if(ch==’%’){
ans=N1%N2;
cout<<ans<<endl;
}
else if(ch==’/’){
ans=N1/N2;
cout<<ans<<endl;
}
else{
cout<<“Invalid operation. Try again.”<<endl;
}

}
while(ch=='x' || ch=='X');
return 0;

}

@Muazul-Hasan-1306054032879326 while loop should break if ch ==‘x’ or ch==‘X’ but you are running your while loop for opposite.and use simple while loop here, do-while may give wrong answer by printing an extra line here.

done that still output is wrong

#4

@Muazul-Hasan-1306054032879326 you have to take N1 and N2 input only when ch is valid. i have updated your code a little look at this https://ide.codingblocks.com/s/269520
