cin >> length;
for (int i = 0; i < length; i++) {
reverseArray[i] = origArray[length - i - 1];
}// for loop that sets the digits in the right order
cout << "Number to guess: ";
for (int i = 0; i < length; i++) {
cout << reverseArray[i];
if (i < length-1)
cout <<"-";
}// for loop that outputs the digits with a dash
}// what runs when 0 is selected
break;
default: {
while(temporary < choice) {
repetition = false;
randNum = rand() % 10;
for (int i = 0; i < choice; i++) {
if (randNum == reverseArray[i])
repetition = true;
}// for loop that sees if random number is equal to inputted
digit value array
if (repetition == false) {
reverseArray[index] = randNum;
index = index + 1;
repetition = repetition + 1;
}// for loop that populates array with random digits
}// while loop that goes through each index of array.
cout << "Number to guess: ";
for (int i = 0; i < choice; i++) {
cout << reverseArray[i];
if (i < choice-1)
cout <<"-";
}//for loop that outputs the digits with a dash
break;
}// what happens when 3, 4, or 5 are selected
}//switch statement
}
每当我运行默认情况时,我都会收到“cygwin_exception::open_stackdumpfile:将堆栈跟踪转储到 class4.exe.stackdump”。我在eclipse中运行它。
这种情况时不时发生,但我不知道为什么它有时会发生。
我将不胜感激任何帮助,因为我没有在网上找到有用的信息。
谢谢
解决方案
在
reverseArray[index] = randNum;
index = index + 1;
repetition = repetition + 1;
这可以通过范围检查条件来防止
if(0 <= index && index < 5){
reverseArray[index] = randNum;
index = index + 1;
repetition = repetition + 1;
}
我不确定这个条件是否会改变你的代码的逻辑,然后如果你输入 0,它会给出一个数字序列,但是对于 3、4 或 5,它会给出一个巨大的循环,几乎就像一个无限循环
