A function is a group of statements that together perform a task. Every C++ program has at least one function, which is main(). A function is known with various names like a method or a sub-routine or a procedure etc. There are two types of Function.
1/ Built-in Function
2/ User Define Function
A C++ function definition consists of a function header and a function body. Here are all the parts of a function −
1/ Return Type
2/ Function Name
3/ Parameters
4/ Function Body
Example :
#include <iostream>
using namespace std;
int sum(int a = 20, int b = 30) /* function with parameters. function name = sum, parameters = a,b & value type = integer. */
{
//function body
int result;
result = a + b;
return (result);
}
int main ()
{
// local variable declaration:
int a = 100;
int b = 200;
int result;
// calling a function to add the values.
result = sum(a, b);
cout << "Total value is :" << result;
return 0; // return value.
}

Would you like for me the explain the function of functions? It's exactly that. Set of code that has a particular purpose, a particular function, that can be called upon from other code.
