给一个二维数组随机赋值

#include <stdio.h>
#include <iostream>

void main()
{
    const char alphanum[] =
        "0123456789"
        "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
        "abcdefghijklmnopqrstuvwxyz";
    const int dimon = 10;
    const int size = 11;
    char **data =  new char*[dimon*size];

    for (int i = 0; i < dimon; i++) {
        data[i]=new char[size];
        memset(data[i],0,size);
    }
    

    for (int i = 0; i < dimon; i++) {
        memcpy(data[i],"Gh0st",5);
        for (int j = 5; j < size; j++) {
            data[i][j] =alphanum[rand() % (sizeof(alphanum) - 1)];
        }
        
    }

    getchar();
    return;

}

运行后， 在 immidiatly  窗口可以查询到
