Lower Triangular Matrix example in C++2 min read

In this article, you will learn how to Write a program to convert a square matrix into a lower triangular matrix in C++.


You should have knowledge of the following topics in the C++ programming language to understand this program:

  • C++ #define directive
  • C++ Functions
  • C++ main() function
  • C++ for loop statement
  • C++ if-else statement
  • C++ cin object
  • C++ cout object

Source Code:



In this program, we have defined the size of the matrix is 4 using the C++ #define directive.

Also, made a custom function named CheckLowerTriangularMatrix() to check the given matrix is Lower Triangular Matrix or not.

Then taken 16 elements 4 x 4 = 16 as inputs from the user to derivate this.

Then we passed the matrix into CheckLowerTriangularMatrix() function and It checked for perhaps condition is matching or not.
