Question

Write a programm create a 4*4 matrix.Display it also find the sum of upper triangle and product of lower triangle

Answer 1

Answer:

Step-by-step explanation:

Input : matrix[3][3] = {1 2 3

4 5 6

7 8 9}

Output :

Lower : 1 0 0 Upper : 1 2 3

4 5 0 0 5 6

7 8 9 0 0 9

Input : matrix[3][3] = {7 8 9

3 2 1

6 5 4}

Output :

Lower : 7 0 0 Upper : 7 8 9

3 2 0 0 2 1

6 5 4 0 0 4

Steps:

For lower triangular matrix, we check the index position i and j i.e row and column respectively. If column position is greater than row position we simply make that position 0.

For upper triangular matrix, we check the index position i and j i.e row and column respectively. If column position is smaller than row position we simply make that position 0.
