[英]How to end while-loop in a nested-if statement within the loop? (probably easy)
下面的代碼是數字猜謎游戲的一部分,其中計算機生成用戶指定范圍內的隨機數。 在這里,我試圖將用戶限制為10個猜測。 如果他/她超過10,則游戲結束:
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)
我收到的輸出只有1/2正確。 例如,假設計算機生成的數字12在1至100的范圍內。 在用戶的第10次(最后一次)猜測中,它將打印:“ GAME OVER ...”; 但是,如果用戶的猜測太低或太高(我不希望這樣做),它也會打印。
我要進行哪些更改以更正此錯誤? 我認為這與嵌套if中的'break'語句有關。
您的問題似乎有效。 該代碼是正確的,它正在執行應做的事情。 但是,編寫相同代碼的更好,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
