What does control reaches end of non void function mean?
If we run this c++ code it works fine and terminates but we get an error at the 8th line saying control reaches end of non-void function. To understand this error we first have to understand the working of the compiler a bit in detail. There are two important kinds of error which occurs while running a program.
Why is there no return statement after for loop?
You are getting this error because if your for loop breaks due to breaking condition i < n; then it don’t find any return statement after for loop (see the below, I mentioned in code as comment). If for loop break due to i >= n then control comes to the position where I commented and there is no return statement present.
Why do we get an error when the function fun is false?
The compiler is just checking the syntax and it interprets that for the function fun if the if condition is false, the flow of the program will reach line 8 and it won’t be returning any value and therefore we get the error.
When do infinite loops fall under run time error?
