Question

我正在尝试创建一个带有5个输入整数的程序，并在其位置打印出星号。我必须创建第二个函数来传递变量以将其打印出来，但只能传递1个值。这是我感到困惑的地方，因为我们还没有超过阵列，我认为这可能是一种可能的方法来完成它？有人指出我应该朝这个方向前进吗？

目前到目前为止：

int main()
{
//Variables
int counter = 1;
int chart = 0;
//I/O section for user input
printf ("Please enter number of asterisks for 5 graphs, must be less than or equal to 50\n");
for (counter; counter <= 5; counter++)
    {
        do
        {
          printf("How long is chart %d? ", counter) ;
          scanf("%d", &chart) ;
        }while (chart > 50) ;
    }
}

在我知道它必须传递给另一个函数之前，我最初有类似下面的内容：

int main()
{
//Variables
  int chart1 ;
  int chart2 ;
  int chart3 ;
  int chart4 ;
  int chart5 ;
//I/O section for user input
    printf ("How long is chart 1? ");
    scanf("%d", &chart1 );
    if (chart1 <= 50)
    {
      printf("\nPlease enter a number less than or equal to 50") ;
    }
    else
    {
    printf ("How long is chart 2? ");
    scanf("%d", &chart2 );
    printf ("How long is chart 3? ");
    scanf("%d", &chart3 );
    printf ("How long is chart 4? ");
    scanf("%d", &chart4 );
    printf ("How long is chart 5? ");
    scanf("%d", &chart5 );
    }
//Chart 1 Print, loop, and counter
      do
      {
        printf ("1.  %d|", chart1);
        for (chart1; chart1 >0; chart1--)
        {
          printf("*");
        }
      } while(chart1 != 0);
//Chart2 Print, loop, and counter
    ....
//Chart 3 Print, loop, and counter
   ..
//Chart 4 Print, loop, and counter
   ..
//Chart 5 print, loop, and counter
    ..
}

以下是如何将整数数组传递给函数：

#include <stdio.h>

void print_array(int arr[]);

int main()
{
    int my_array[] = { 1, 2, 3, 4, 5 };

    print_array(my_array);

    return 0;
}

void print_array(int arr[])
{
    int i;

    for (i = 0; i < 5; ++i)
        printf("%d ", arr[i]);
    printf("\n");
}

Answer 2

可能这可能就是你要找的东西：

. /home/user/.bashrc

你的方法定义可以使用参数显示星号的for循环（不完全是这样的）：

for (counter = 0; counter < 5; counter++) //notice changes here as well
    {
          printf("How long is chart %d? ", counter) ;
          scanf("%d", &chart) ;
          changeToAsterisk(chart);
    }
