Question

What is the meaning of function overloading.

Answer 1

Function overloading (also method overloading) is a programming concept that allows programmers todefine two or more functions with the same name and in the same scope. Each function has a unique signature (or header), which is derived from:function/procedure name. number of arguments. arguments' type.

Answer 2

Functions having the same name but different arguments is termed as “function overloading”.

Explanation:

For example you want to add some values, sometimes you want to add two values, sometimes three values, then you can opt for function overloading.

void sum(int x, int y)

{

printf(“%d”, x + y);

}

void sum(int x, int y, int z)

{

printf(“%d”, x + y + z);

}

You can differ by number of argument or same number of argument with different type.
