C Program to find Lower Triangle Matrix

What is a matrix?

Prerequisites

Before starting with the tutorial, we assume that you are the best aware of the following C programming topics:

Operators in C Programming.
Basic Input and Output function in C Programming.
Basic C programming.

For loop in C programming.

What is a matrix?

A matrix is a multidimensional phenomenon and is created with the help of a 2d array having multiple rows and columns.

Algorithm:-

With the help of this program, we can find Lower Triangle Matrix.

1. Declaring the variables for the program.

2. Taking the input size of matrix.

3. Taking the input elements of matrix.

4. Creating the Lower <strong>Triangle Matrix.</strong>

5. Printing the<strong> Lower Triangle Matrix</strong>.

6. End Program.

Program to find Lower Triangle Matrix:-

In this tutorial, we will create a multidimensional array with the help of C programming. First, we will take the size of the matrix from the user, and then we will take the input elements. Now we will create a Lower triangle in the matrix by adding a zero in rows from the right corners. At last, we will print the lower matrix triangle.

Program:-

/* C Program to find Lower Triangle Matrix */
 
#include<stdio.h>
 
int main()
{
    //Declaring the required variables for the program
 	int i, j, x, z, a[10][10];
    
    //Taking the size or the 2d array / matrix
 	printf("\n Please Enter Number of rows and columns  :  ");
 	scanf("%d %d", &i, &j);
    //Taking the elements of the matrix.
 	printf("\n Please Enter the Matrix Elements \n");
 	for(x = 0; x < i; x++)
  	{
   		for(z = 0;z < j;z++)
    	{
      		scanf("%d", &a[x][z]);
    	}
  	}
    //Creating the lower triangle matrix from the given matrix
 	for(x = 0; x < i; x++)
  	{
  		printf("\n");
   		for(z = 0; z < j; z++)
    	{
    		if(x >= z)
    		{
    		    //Printing the lower triangle matrix.
    			printf("%d ", a[x][z]);
			}
			else
			{
				printf("0  ");
			}
   	 	}
  	}
  	
 	return 0;
}

/* C Program to find Lower Triangle Matrix */

#include<stdio.h>

int main()

{

//Declaring the required variables for the program

int i, j, x, z, a[10][10];

//Taking the size or the 2d array / matrix

printf("\n Please Enter Number of rows and columns : ");

scanf("%d %d", &i, &j);

//Taking the elements of the matrix.

printf("\n Please Enter the Matrix Elements \n");

for(x = 0; x < i; x++)

{

for(z = 0;z < j;z++)

{

scanf("%d", &a[x][z]);

}

//Creating the lower triangle matrix from the given matrix

for(x = 0; x < i; x++)

{

printf("\n");

for(z = 0; z < j; z++)

{

if(x >= z)

{

//Printing the lower triangle matrix.

printf("%d ", a[x][z]);

}

else

{

printf("0 ");

}

return 0;

}

Output:-

In the above program, we have first initialized the required variable.

a[10][10]= it will hold the integer value.
x = it will hold the integer value.

z = it will hold the integer value.
i= it will hold the input integer value for rows.
j= it will hold the input integer value for columns.
