Write a program that calculates and displays the product of the even numbers from 1 to 8 using the while loop

We learn Programming to solve problems using Computers. A Computer Program is the set of instructions that are given to a computer so that it can solve problems. To solve problems is our primary goal in Computer Science.

C++ is the most fundamental language to learn programs. C++ is the High-Level Language.  It is very easy to instruct computers using C++ Programming Language. My goal is to provide Practice Programs. Because As we know practice is the most fundamental aspect to learn how to program. I will provide solved programming exercises to help students.

What is Compiler?

A Compiler is computer software that is used to convert a C++ language program to a computer’s native language which is binary language. It is a translator program. It is used to convert Source Code into Object Code.

What is Source Code?

Any instruction that is written in High-Level Language i.e. C++ or C is known as Source Code.

What is Object Code?

Any Code that is written in Low-Level Language i.e. Assembly Language or Binary Language is known as Object Code.

So we will use Dev C++ Compiler for C++ Programming.

What is Loop in C++?

In some cases, we have to repeat a statement or set of statements a certain number of times. This repetition is known as a loop. Commonly loop has three main parts

1. Initialization
2. Condition
3. Increment / Decrement

There are thee main types of Loops.

1. While Loop
2. Do-While loop
3. For Loop

While Loop

While loop is used to repeat a statement or set of statements again and again until the condition remains true. While loop checks the condition first and then executes the statements. While loop is used when the number of iterations is unknown in advance.

Syntax of While Loop

while(condition)
{
      //body
      //increment/Decrement
}

Do while Loop

The do-While loop is used to repeat a statement or set of statements again and again until the condition remains true. Do-While loop first executes the body of the loop then checks the condition. Do-While Loop is used when the number of iterations is unknown.

Syntax of Do-While Loop

do
{
   //body of do-while loop
}while(condition);

For Loop

The For loop is used to repeat a statement or set of statements again and again until the condition remains true. For Loop is used when the number of iterations is known.

Syntax of For Loop

for(initialization, condition, increment/.decrement)
{
  //body of For Loop
}

So Let’s Write Some Code.

Write a program that calculates and displays the product of the even numbers from 1 to 8 using the while loop.

#include<iostream>
using namespace std;
main()
{
int prod = 1, n = 1;

while(n<=8)
{
if(n%2 == 0)
{
cout<<n<<endl;
prod = prod*n;
}
n++;
}
cout<<"Product = "<<prod;
}
