C Program for printing the lower triangle elements in a matrix
In this section, we are writing a program for printing the lower triangle ( lower diagonal ) elements of a given matrix with order mXn. (m==n) i.e. it should be a square matrix.
For example, if the order of matrix is 3X3.
Then, to do this, we require one input matrix.
For example:
First matrix:
1 2 3
3 4 6
7 8 9
result is : 2 3 6
To write this program, do the following things.
Step 1: read the order of the first matrix
Step 2: read the first matrix
Step 3: write the condition for checking the lower triangle elements and print the result.
Observe the following diagram
assume the given matrix is
1 2 3
4 5 6
7 8 9
if we use the condition
i==j ; we get diagonal elements
i>j ; we get lower diagonal elements
i<j ; we get upper diagonal elements.
Output:
Enter the number of rows and columns of matrix
3
3
Enter the elements of first matrix
1 2 3
4 5 6
7 8 9
4 7 8
i<j ; we get upper diagonal elements.
use this condition in the above program to get upper diagonal elements.
Output:
Enter the number of rows and columns of matrix
3
3
Enter the elements of first matrix
1 2 3
4 5 6
7 8 9
2 3 6
