## Overview
The `if` statement in C++ is  used to specify a block of code that will be executed if a condition provided is `true`.

## Syntax
```
if (condition){
  statement
}
```
 The `statement` or command will execute provided the given `condition` is `true`. 


## Example
Let's write a code using the `if` statement:




#include <iostream>
using namespace std;

int main() {
  // creating a condition 
  if (2 > 1) {

    // creating a statement/block of code to be executed
    cout << "2 is greater than 1";
    
  }  
  return 0;
}


## Explanation
* Line 6: We use the `if` statement. We create a condition, if the number `2` is greater than `1`, the block of code or statement in line 9 should be executed.
* Line 9: we create a statement or block of code to be executed provided that the condition in line 6 is `true`.


We can also use the `if` statement to test variables.

## Example



#include <iostream>
using namespace std;

int main() {
  // creating variables
  int x = 1;
  int y = 2;

  // creating condition 
  if (x < y) {

    // statement/block of code to be executed 
    cout << "x is less than y";
  }  
  return 0;
}


## Explanation 
* Line 6 and 7: We create integer variables `x` and `y`.

* Line 10: We compare the values of `x` and `y`. If `y` is greater than `x` then the condition is `true`.

* Line 13: We create a statement or block of code to execute provided the condition given in **line 10** is `true`.

How to use the if statement in C++

The if statement in C++ executes a block of code if a specified condition is true.
