It's a code that randomly allocates two fruits per player, but the following sentence of this code is not executed. I'm not sure if I'm a beginner Help me.
c++
for (int i = 0; i < 8; i++) {
while (1) {
fruit_1[i] = fruit[rand() % 8];
found1 = 0;
for (int j = 0; j < i; j++) {
if (fruit_1[j] == fruit_1[i])
found1 = 1;
}
if (found1 == 0){
Break; If no value such as //, end random number regeneration
}
In the
One. fruit_1[i] = fruit[rand()%8]; After getting a random fruit name,
2-1. If fruit_1 has the same fruit in the while group, pick the fruit again.
2-2. If fruit_1 does not have the same fruit in the while group, put the fruit in the array.
3. Repeat the above process 8 times (inti = 0; i < 8; i++).
The problem is that string fruit [8] = { "Apple", "Apple", "Grape", "Grape", "Grape", "Melon", "Melon", "Tangerine" }; contains two elements of the same value.
So when I = 4, fruit_1 contains all of the words "apple," "grape," "male," and "tangerine
After this, fruit_1[i] = fruit[rand()%8]; is forced to pull the value contained in fruit_1.
Therefore, the new value cannot be drawn, and the found1 == 0 cannot be caught, resulting in an infinite loop.
By any chance fruit_1 = {"Apple", "Grape", "Apple", "Grape", "Melon", "Tangerine", "Melon"} If you want to put each fruit in random order twice in fruit_1 like this,
while (1) {
fruit_1[i] = fruit[rand() % 8];
found1 = 0;
for (int j = 0; j < i; j++) {
if (fruit_1[j] == fruit_1[i])
found1 ++;
}
if (found1 <= 1){
Break; If no value such as //, end random number regeneration
}
}
Change the code like this.
