Question 2 COS1511 Assignment 2: Debugging Errors in functions
Correcting errors in output code 2i
To call a function, simply do the following;
int main()
{
function1();
return 0;
}
Do not do the following in terms of calling functions
a) endl; int function2()
b) cout << "Inside function function1 " << endl;
Do the following to correct the above errors when calling functions in C++
• Always include the function you created within the main function within the default int
main () function.
• Never include endl;when ending functions , simply use the {} to end functions
• You cannot call a function without stating it in int main()
