}找错
I've reviewed the code, and there are several issues that need to be addressed. Here's a list of the errors and suggestions for fixing them:
In the input_char function:
} at the end.if (str[i] == " ") is incorrect. It should be if (str[i] == ' ') (single quotes for a character).p variable is not being reset between iterations, which may cause unexpected behavior.if (p == 9) will never be reached as p is only incremented to a maximum of 2.In the max_strings function:
In the main function:
Here's the corrected input_char function:
void input_char(char *str) {
int i, p = 0;
while (1) {
scanf("%s", str);
if (strlen(str) > 8) {
printf("输入错误，字符串长度超过了8个字符，请重新输入！\n");
continue;
}
p = 0;
for (i = 0; i < strlen(str); i++) {
if (str[i] == ' ') {
printf("输入错误，字符串不能有空格，请重新输入！\n");
p = 1;
break;
}
}
if (p == 0) break;
}
}These changes should resolve the issues in the code. The main problems were in the input_char function, which had logical errors and syntax issues. The corrected version should properly handle input validation for string length and spaces.
