Question

What does it mean to overload a function? What are the requirements? Give an example of 2 overloaded functions.

Answer 1

To overload, a function means having 2 or more functions with the same name and these functions have different tasks to perform.

The requirements to overload a function are :

1. The overloaded functions must have the same name
2. They must differ in the number of arguments or type of arguments or the sequence of parameters.

Example :

int sum (int a, int b,int c)

{

return (a+b+c);

}

int sum (int a, int b)

{

return (a+b);

}

int sum (float a, float b,float c)

{

return (a+b+c);

}
