Write a program to print upper 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\n The Upper Triangular Matrix is: ");
   for(r = 0; r < rows; r++){
      printf("\n");
      for(c = 0; c < cols; c++){
         if(r > c){
            printf("0");
            printf("\t");
         }
         else{
            printf("%d\t ", matrix[r][c]);

         }
      }
   }
   return 0;
}

Output

Please enter the elements for the Matrix: 
 12 13 14   
 15 16 17
 18 19 20


The Upper Triangular Matrix is: 
 12       13      14      
 0        16      17      
 0        0       20
