program to calculate sum of Upper Triangular Elements in C

#include<stdio.h>
#include<conio.h>

int main() {
   int y, x, a[10][10], sum, rows, columns;

   printf("\nEnter the number of Rows : ");
   scanf("%d", &rows);

   printf("\nEnter the number of Columns : ");
   scanf("%d", &columns);

   //Accept the Elements in Matrix
   for (y = 0; y < rows; y++)
