Program to find if the given matrix is lower triangular or not is discussed here. A square matrix is obtained as input from the user and it is checked if it is lower triangular or not. A square matrix is said to be a lower triangular matrix if all the entries above the diagonal are zero.

- Input the order of the square matrix.
- Input the matrix elements.
- Repeat from i = 0 to n.
- Repeat from j = 1+1 to n.
- if (mat[i][j] != 0)
- Set flag = 0 and print "Not a Lower Triangular Matrix".
- Else, print "Lower Triangular Matrix".

C
