what 's wrong in my code?
acc to question if i type any other character then it is supposed to repeat the whole opeartion,but for how many times.
Passing only three test cases
@shubhamshagy hey Shubham instead of using so much decision control use only one while loop inside while loop take a switch case which takes input as a character and this character decide which case will execute case like +,*/,- and take a default case : cout<<“Invalid operation. Try again.”
note this loop will run until you hit character like X or x
eg
cin>>ch;
while(ch!=‘x’&&ch!=‘X’)
{
switch(ch){
case ‘+’: {
break;
}
case '-': {
break;
}
case '*': {
break;
}
case '/': {
break;
}
default : cout<<"Invalid operation. Try again."<<endl;
break;
}
cin>>ch;
}
}
I hope you will get my point 
but switch is not taught yet…
@shubhamshagy I discussed the easy version with you just take input in between and you are done
switch work based upon input given we are given character based upon the character the case will execute if character is non of these cases the default will work you don’t have to write all possible character
@shubhamshagy on line no 21 you didn’t output your result and put endl in each output line in default also
@shubhamshagy hey shubham your output should match with sample one so correct line no 22 endl and
put dot on default output line "Invalid operation. Try again"as “Invalid operation. Try again.”
