输入一个正整数n(n<=6)，再输入n×n的矩阵，求其主对角线元素之和及副对角线元素之和并输出。

#include <stdio.h>
#include <stdlib.h>

int main()
{
	int n;
	int i, j;
	int PriDiagonal = 0;  //主对角线和
	int DepDiagonal = 0;  //副对角线和
	scanf("%d", &n);
	int **matrix = (int*)malloc(n * sizeof(int*));
	for (i = 0; i < n; i++)
	{
		matrix[i] = (int *)malloc(n * sizeof(int));
		for (j = 0; j < n; j++)
		{
			scanf("%d", &matrix[i][j]);
		}
	}
	for ( i = 0; i < n; i++)
	{
		PriDiagonal += matrix[i][i];
		DepDiagonal += matrix[i][n - i-1];
	}
	printf("%d %d", PriDiagonal, DepDiagonal);
}
