{
char checkcode[63]={'q','w','e','r','t','y','u','i','o','p','a','s','d','f','g','h','j','k','l','z','x','c','v','b','n','m','Q','W','E','R','T','Y','U','I','O','P','A','S','D','F','G','H','J','K','L','Z','X','C','V','B','N','M','0','1','2','3','4','5','6','7','8','9'}

int m=rand()%62;
ch[i]=checkcode(m);

Answer 1

1,定义数组后面少“；”号
2，checkcode(m) ，这是数组，不是函数
这些问题自己跑一下就出来了
