C语言之获取32字节随机数的字符串

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 32

void 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
