Write a program to print lower triangular array of given array.

#include<stdio.h>
int main() 
{
   int rows, cols, r, c, matrix[10][10];
   printf("Please enter the number of rows for the matrix: ");
   scanf("%d", &rows);
   printf("\n");
   printf("Please enter the number of columns for the matrix: ");
   scanf("%d", &cols);
   printf("\n");
   printf("Please enter the elements for the Matrix: \n");
   for(r = 0; r < rows; r++){
      for(c = 0;c < cols;c++){
         scanf("%d", &matrix[r][c]);
      }
   }
   printf("\n The Lower Triangular Matrix is: ");
   for(r = 0; r < rows; r++){
      printf("\n");
      for(c = 0; c < cols; c++){
      if(r >= c){
         printf("%d\t ", matrix[r][c]);
      }
      else{
         printf("0");
         printf("\t");
      }
   }
   }
   return 0;
}

Output

Please enter the number of columns for the matrix: 3

Please enter the elements for the Matrix: 
90 91 92
93 94 95
96 97 98

The Lower Triangular Matrix is: 
90       0       0
93       94      0
96       97      98
