Use A Conditional To Check Less Than Number In C++

C++ programming language provides a straightforward way to conduct comparisons among variables. One of the comparison operators in C++ is the less than operator, which checks if one value is less than another.

Code snippet for Less Than Condition

Here is a simple example of this operator in action:

#include<iostream>
using namespace std;

int main() {
   int num1 = 15;
   int num2 = 20;

   if(num1 < num2) {
      cout << "num1 is less than num2";
   } else {
      cout << "num1 is not less than num2";
   }
   return 0;
}

In this code, we are comparing two integers num1 and num2 to ascertain whether num1 is less than num2 or not.

Code Explanation for Less Than Condition

The detailed explanation of the above code snippet is as follows:

1. Include the header file: #include<iostream> is a preprocessor command that includes the iostream header file in the program. This file is required for input/output operations.

2. Declare namespace: using namespace std; is a line of code that tells the compiler to expect the names of objects and variables from the standard library.

3. Define the main function: The int main() function is the entry point of the program. The execution of program begins from here.

4. Declare variables: We declare two integers, num1 and num2, and initialize them with the values 15 and 20, respectively.

5. Conditional Statement: We then use the if statement, a conditional construct, to check if num1 is less than num2. If the condition is true, the string “num1 is less than num2” gets printed. Otherwise, it prints “num1 is not less than num2”.

6. Ends Program: The return 0; statement signifies the successful termination of the program.

This simple less-than operator can be incredibly useful when implemented in loops, sorting algorithms, numerical computations, and many other areas where relative value comparisons are required. So, try to get comfortable with this operator if you’re planning to do a deep dive into C++ programming.
