c语言猜数提前跳出for循环

在 C 语言中,如果你想要编写一个猜数字游戏,通常会有一个 for 循环让玩家猜测直到猜对为止。如果在用户猜数的过程中想要通过某个条件提前结束循环,你可以检查当前的猜测值是否满足特定的退出条件,比如达到最大允许次数或者猜对了。
下面是一个简单的例子,假设我们设置了一个固定的目标数字 `target` 和最大尝试次数 `max_tries`:
```c
#include <stdio.h>
#include <stdlib.h>
int main() {
int target = 42; // 随机目标数字
int guess;
int tries = 0;
printf("Welcome to the Guessing Game! I'm thinking of a number between 1 and 100.\n");
for (guess = 1; guess <= 100 && tries < max_tries; ++guess) {
printf("Enter your guess: ");
scanf("%d", &guess);
if (guess == target) {
printf("Congratulations! You guessed it correctly in %d tries!\n", tries + 1);
break; // 猜对了,直接跳出循环
} else if (guess > target) {
printf("Too high! Try again.\n");
} else {
printf("Too low! Try again.\n");
}
++tries; // 每次尝试增加计数
}
if (guess > target) {
printf("Sorry, you didn't guess within %d tries. The target was %d.\n", max_tries, target);
}
return 0;
}
```
在这个示例中,当玩家猜对数字或者达到最大尝试次数时,`break` 语句会使得循环提前终止。如果用户没有在规定次数内猜对,程序将显示结果并退出循环。
