[英]How to end while-loop in a nested-if statement within the loop? (probably easy)
下面的代码是数字猜谜游戏的一部分,其中计算机生成用户指定范围内的随机数。 在这里,我试图将用户限制为10个猜测。 如果他/她超过10,则游戏结束:
int t1 = 0;//stores # of guesses
while(true){//loop begins
t1++;//increments each iteration to represent # of guesses
if(g1!=n){//if the guess is incorrect... (n = # user is trying to guess)
if(t1>10){//# of guesses cannot exceed 10
System.out.println("\nGAME OVER\nYou have exceeded the max # of tries!");
break;}//game ends if user exceeds max # of attempts
if(g1<n){System.out.println("\nGuess Higher!\n" + t1 + "attempt(s) so far");
continue;}//guess is too low
if(g1>n){System.out.println("\nGuess Lower!\n" + t1 + " attempt(s) so far");
continue;}}//guess is too high (loop ends)
我收到的输出只有1/2正确。 例如,假设计算机生成的数字12在1至100的范围内。 在用户的第10次(最后一次)猜测中,它将打印:“ GAME OVER ...”; 但是,如果用户的猜测太低或太高(我不希望这样做),它也会打印。
我要进行哪些更改以更正此错误? 我认为这与嵌套if中的'break'语句有关。
您的问题似乎有效。 该代码是正确的,它正在执行应做的事情。 但是,编写相同代码的更好,更有效的方法是:
// run a for loop that will let user guess 10 times
for (int i = 0; i < 10; i++)
{
// see if the guessed number is incorrect
if (g1 != n)
{
// check whats wrong with the number entered
// number of guesses cannot exceed 10
if ((i+1) >= 10)
{
System.out.println("\nGAME OVER\nYou have exceeded the max # of tries!");
}
else if (g1 < n)
{
// if user's guess is less than the number
System.out.println("\nGuess Higher!\n" + (i+1) + "attempt(s) so far");
}
else if (g1 > n)
{
// if user's guess is greater than the number
System.out.println("\nGuess Lower!\n" + (i+1) + " attempt(s) so far");
}
}
} // for loop ends
