Write a 'C' Program to calculate sum of elements of upper triangle of a n * n matrix.

#include

void main()
{
    int m[10][10],i,j,n,sum = 0;
    clrscr();
    printf("ENTER NUMBER OF ROWS OR COLOUMNS OF SQUARE MATRIX ::>\n");
    scanf("%d",&n);
    printf("ENTER ELEMENTS OF %d * %d MATRIX ::>\n",n,n);
    for(i = 0 ; i < n ; i++)
    {
        for(j = 0 ; j < n ; j++)
        {
