收到一个介于 0 和 120 之间的数字
receives a number between 0 and 120
我正在尝试让程序不断询问该人的年龄,直到程序收到 0 到 120 之间的数字。我已经设置了一个 do while 循环,但我收到一条错误消息,任何帮助将不胜感激。
{
string name = get_string("What's your name?\n");
printf("Hello, %s\n", name);
sleep(1);
do
{
int age = get_int("How old are you?\n");
}
while (age < 1 || age > 120)
printf("Wow, %s you've been around for atleast %i days!\n", name, age * 365);
sleep(1);

int age;
do {
age = get_int("How old are you?\n");
}
