输入M*N阶矩阵A和B，用函数编程计算并输出A与B之和

#include<stdio.h>
#define M 2
#define N 3
void scanfjuzhen(int arr[M][N])//向二维数组输入数据
{
	int i = 0;
	int j = 0;
	for (i = 0; i < M; i++)
	{
		for (j = 0; j < N; j++)
			scanf("%d", &arr[i][j]);
	}
}
void sumjuzhen(int a[M][N], int b[M][N],int c[M][N])//计算A与B的和并存与C中
{
	int i =0 ;
	int j = 0;
	int sum = 0;
	for (i = 0; i < M; i++)
	{
		for (j = 0; j < N; j++)
		{
			c[i][j] = a[i][j] + b[i][j];
		}	
	}
}
int main()
{
	int a[M][N];
	int b[M][N];
	int c[M][N];
	int i = 0;
	int j = 0;
	printf("输入a矩阵元素的值：");
	scanfjuzhen(a); //调用scanfjuzhen()函数，向二维数组A中输入数据
	printf("输入b矩阵元素的值：");
	scanfjuzhen(b); //调用scanfjuzhen()函数，向二维数组B中输入数据
	sumjuzhen(a, b,c);//计算A与B的和并存与C中
	printf("A与B的和的矩阵C为：\n");
	for (i = 0; i < M; i++)
	{
		for (j = 0; j < N; j++)
		{
			printf("%d ", c[i][j]);
		}
		printf("\n");
	}
	return 0;
