Plz help me with this code!? when i write this code there is no compiler error but i end up with endless lope

Question

int num;
x:for(;cin>>num;){
//some code
//this for built so it won't end and keep taking numbers
}
cout <<"this is not a number plz enter a number";
goto x;

so when the user enter a string instead of a number it enter an endless loop .
how do i break this , and make it say enter a number without ending the program or initializing an endlees loop.

Answer 1

You haven't entered the test expression which checks and continue the loop that is the limit of loop that is the reason your loop is going endlessly.

To enter a string you should use an array of maximum size as you prefer and use cin.getline to input the string.
