C++ if

Hello everyone
today we will talk about if in C++

You can use these conditions to perform different actions for different decisions

The C++ programming language has the following selection statements:

1. Use if to specify a block of code to execute if a specified condition is true.

2. Use else to define a block of code that executes if the first condition is false.

3. If the first condition is false, use else if to specify a new condition to test.

4. Use a switch to specify multiple alternative blocks of code to be executed.

The if statement.

if - Use the if statement to specify a block of C++ code to execute if a condition is true.

if (condition) 
{
  // block of code to be executed if the condition is true
}

Note that if written in lowercase letters. Converting to uppercase (IF or IF) will cause an error.

In the following example, we test two values ​​to determine whether 20 is greater than 18. If the condition is true, print the text:

#include <iostream>
using namespace std;

int main()
{

int num 80;
int num1 = 70;

if(num > num1)
{
cout << "80 is greater than 70";
}

return 0;
}
