Example C++ Program:

#include <iostream>

using namespace std;

int main() // 'main' function of the program, everything starts here

{

double loan, loan_tax; // Declare variable, doubles for decimal values

double loan_rate=0.03; // Set loan_rate  variable to 0.03 for 3%

cout << “Enter loan amount:”<<endl; // Output to console

cin >> loan; // Wait for user input, and store it into the loan variable (as a decimal value)

loan_tax = loan_rate * loan;  // Calculate loan_tax and store result into loan_tax variable

cout << “The loan tax is “<<loan_tax<<endl; //Output "The loan tax is" to the terminal, 

// followed by the value in the variable 'loan_tax'

return 0; // Exit the program safely

}

For while loop and for loop 

In the above video you can see the basic implementation of the while loop and for loop by taking an example of factorial of a number. For the for loop you guys will be seeing the example of a infinite loop here.
