1、问题

获取32字节随机数的字符串

 

 

 

2、代码实现

 

#include <stdio.h>
#include <time.h>
#include <stdlib.h>#define SIZE 32void get_rand(char *p,  int length) {	char value[10] = "0123456789";srand(time(NULL));for (int i = 0; i < length; ++i) {*(p + i) = value[rand() % 10];}*(p + SIZE) = '\0';return;
}
int main() 
{unsigned char value[SIZE] = {0}; get_rand(value, SIZE);printf("value is: %s\n", value);return 0;
}

 

 

 

3 运行结果

value is: 37395579854277531124503372363886
