Loops in C++

First of all i want to show you the book by which iam now a pro in c++ .You can buy it by clicking here

• Loops

Loops are used to repeat a block of code.This also helps you by saving your time ,reducing errors and making code readable.There are 3 loops in c++ .

• For loop

A for loop enables a particular set of conditions to be executed repeatedly until a condition is satisfied

• Example

#include <iostream>

using namespace std;

int main(){

   int i=1; while(i<=6) {

      cout<<"Value of variable i is: "<<i<<endl; i--;

   }

}

• While Loop

In While loop we give a condition and the loop continues until the condition becomes false. 

• Example

 int pro = 0; 

while ( pro < 5) {

 cout << pro << "\n";

 pro++; 

} 

In the above example (i<5) is a condition and the loop will continue until it becomes false

• Do While loop

 This loop is also like while loop but it executes code before condition

• Example

int i = 0;

do {

  cout << i << "\n";

  i++;

}

while (i < 5);

 Condition will be executed after code block as we can see that while is after the code
