Sum of principal diagonal elements and square roots of sum of square of all even elements using pointer - C

Q.Write a program using pointer to input a mxn matrix and find the following
(a)sum of principal diagonal elements
(b)square roots of sum of square of all even elements

==> Code goes like this:

#include<stdio.h>
#include<conio.h>
#include<math.h>
#define SIZE 10
int main()
{
    int a[SIZE][SIZE],i,j,n,sum=0,sume=0,temp;
    printf("Enter the dimension of matrix: ");
    scanf("%d",&n);
    printf("Enter element of matrix: ");
    for(i=0;i<n;i++)
    {
        for(j=0;j<n;j++)
        {
            scanf("%d",*(a+i)+j);
        }
    }
   
    for(i=0;i<n;i++)
    {
        for(j=0;j<n;j++)
        {   
            temp=*(*(a+i)+j);       
            if(temp%2==0)
            {
                sume+=(temp*temp);
            }
       
            if(i==j){
           
            sum+=*(*(a+i)+j);
           
                    }
        }
    }
    printf("Sum of diagonals is: %d ",sum);
    printf("\nThe square root of sum of square of even elements: %.2f ",sqrt(sume));
    getch();
    return 0;
}

Output:

If you are using Turbo C++ IDE, then use conio.h in link section after stdio.h
and use getch(); to hold the output screen, just before the end of main function.
If you have any confusion regarding the program, please, comment below.
Happy Coding !
Thank you
