Your program gives the following warning on compilation:
Computer Science homework question answer, step 1, image 1
It is because the compiler can not tell that if the function will return something. Because in a scenario of variable 'argc' having a value equal to less than 0, 'for' loop will never run and the compiler doesn't know what return. You have to make sure that the program is returning a value irrespective of conditional statements.
