Question

確かに問題はアドレスまたはポインタであると思いますが、見つけられません。誰かが問題を説明することはできますか？

私の問題は、プロンプトが表示されたら入力した内容を印刷しないことです。

void getData(int* enterhour, int* enterminute, int* exitotalhour, int* exminute); 
void rate(int exitotalhour, int exminute, int enterhour, int enterminute, int* totalhour, int* totalminute, int* round);

    return;

Answer 1

resultにパラメータがint*なので、あなたはprintfでそれらを解除参照する必要はありませんか？

printf("\nTIME-IN\t\t %d:%d", *enterhour, *enterminute); 

Answer 2

私はあなたの問題は、この機能であると信じて：

void getData(int* enterhour, int* enterminute, int* exitotalhour, int* exminute) 
{ 
    char v; 

    printf("Enter c for car, b for bus, t for truck: "); 
    scanf("%c", &v); 
    printf("\nHour vehicle entered 0-24: "); 
    scanf("%d", &enterhour); 
    printf("\nMinute vehicle entered 0-60: "); 
    scanf("%d", &enterminute); 
    printf("\nHour vehicle exited 0-24: "); 
    scanf("%d", &exitotalhour); 
    printf("\nMinute vehicle exited 0-60: "); 
    scanf("%d", &exminute); 
    return; 
} 

あなたが関数にint型のポインタを渡し、その後、scanfにこれらのポインタのアドレスを与えています。

void getData(int* enterhour, int* enterminute, int* exitotalhour, int* exminute) 
{ 
    char v; 

    printf("Enter c for car, b for bus, t for truck: "); 
    scanf("%c", &v); 
    printf("\nHour vehicle entered 0-24: "); 
    scanf("%d", enterhour); 
    printf("\nMinute vehicle entered 0-60: "); 
    scanf("%d", enterminute); 
    printf("\nHour vehicle exited 0-24: "); 
    scanf("%d", exitotalhour); 
    printf("\nMinute vehicle exited 0-60: "); 
    scanf("%d", exminute); 
    return; 
}
