记得有个程序题，是写出个类似《黑客帝国》里面数据流的程序，这两天复习复习C语言，觉得还挺好玩的(只为好玩)

#include <time.h>#include <stdio.h>#include <stdlib.h>#define N 150int main (void) {   int x, max = 0, n = 20000, i = 0, j = 0, k = 0, area[N] = {0};   char print_format[N], print_shape[10] = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9'};   srand((int)time(0));   for (i = 0; i < n; i++) {       x = rand() % N;       area[x]++;   }   for (i = 0; i < N; i++){       if (max < area[i])           max = area[i];   }   for (i = 1; i <= max; i++) {       for ( k = 0; k < 20000000; k++);       for ( j = 0; j < N; j++) {           if ( i > area[j] )               printf(" ");           else {               x = rand() % 10;               printf("%c", print_shape[x]);           }       }       printf("\n");   }   return 0;}
