functions are building blocks of C++ A function is a named part of a program that can be invoked from other parts of the program as often needed.Consider the following program that accepts a number and prints its cube:-
#include<iostream.h>
using namespace std;
float cube(float);
float cube(float a)
{
return a*a*a;
}
int main()
{
float num;
cout << "Enter a number:";
cin >> num;
cout << "The cube of" << num << "is " << cube(num)<< "\n";
system("pause");
return 0;
}
output of the program will be-
Enter a number : 19
The cube of 19 is 729
