头像换掉我就考虑回答一下

#include <stdio.h>                     
#include <stdlib.h>                    
#include <time.h> 
#define M 4                           
#define N 4                           

int main(void)
{
    int i = 0, j = 0;
    int Arr[M][N] = { { 0 } };

    srand(time(NULL));

    for (i = 0; i < M; ++i)
    {
        for (j = 0; j < N; ++j)
        {
            Arr[i][j] = rand() % 10;
        }
    }

    printf("Array[%d][%d] is: \n", M, N);
    for (i = 0; i < M; ++i)
    {
        for (j = 0; j < N; ++j)
        {
            printf("%d\t", Arr[i][j]);
        }
        printf("\n");
    }
    printf("\n\n");
    for (i = 0; i < M; ++i)
    {
        for (j = 0; j < N; ++j)
        {
            printf("%d\t", Arr[i][j]+'0');
        }
        printf("\n");
    }
    return 0;
}

并没有好啊，我想生成字母

rand 出来是整数，getRandChar()可以得到字母，但总是出错

#include <stdio.h>                     
#include <stdlib.h>                    
#include <time.h> 
#define M 4                           
#define N 4                           

int main(void)
{
    int i = 0, j = 0;
    int Arr[M][N] = { { 0 } };

    srand(time(NULL));

    for (i = 0; i < M; ++i)
    {
        for (j = 0; j < N; ++j)
        {
            Arr[i][j] = rand() % 26+65;
        }
    }

    printf("Array[%d][%d] is: \n", M, N);
    for (i = 0; i < M; ++i)
    {
        for (j = 0; j < N; ++j)
        {
            printf("%c\t", Arr[i][j]);
        }
        printf("\n");
    }
    return 0;
}
