Please re-submit your code using the [ code ] [ /code ] function. That will give you some line numbers to work with and is easier for us to read to help you.

The reason it is displaying 0 because you are returning "0" as the total for each function. You will want to return the marks of each student instead of returning 0.

[mobotus]

int main() {
student1();
student2();
student3();
return 0;
}

You don't need to cout those functions they seem to handle their own console output.

Also your main needs to be int main

And your grade is a float but you pass in all ints when you calculate it did you mean to do that?
