C语言格式化输入不定长数组

Posted 2020-08-08

先随便写写，有空再整理。

直接贴代码

#include <stdio.h>
#include <stdlib.h>

//从一行标准输入中格式化输入一个不定长数组
void inputVec ();

//读入给定行数的不定长数组
void inputVecs1 ();

//读入不确定行数不定长数组
void inputVecs2 ();

void main ()
{
	inputVecs1 ();
	return;
}

void inputVecs1 ()
{
	while (!feof(stdin))
	{
		int size = 0;
		int i = 0;
		int k = 0;
		int arr[64] = {0};

		i = scanf ("%d", &arr[size]);
		k = getchar();
		++size;
		while (EOF != i && ‘,‘ == k && 64 >= size)
		{
			i = scanf ("%d", &arr[size]);
			k = getchar();
			++size;
			printf ("%d:%d ", i, k);
		}

		printf ("\n%d\n",size);

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

	}
}

void inputVecs2 ()
{
	int n = 0;
	int j = 0;
	scanf ("%d", &n);
	while (j < n)
	{
		int size = 0;
		int i = 0;
		int k = 0;
		int arr[64] = {0};

		i = scanf ("%d", &arr[size]);
		k = getchar();
		++size;
		while (EOF != i && ‘,‘ == k && 64 >= size)
		{
			i = scanf ("%d", &arr[size]);
			k = getchar();
			++size;
			printf ("%d:%d ", i, k);
		}

		printf ("\n%d\n",size);

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

		++j;
	}
}

void inputVec ()
{
	int size = 0;
	int i = 0;
	int k = 0;
	int arr[64] = {0};

	i = scanf("%d", &arr[size]);
	k = getchar();
	++size;
	while (EOF != i && size <= 64 && ‘,‘ == k)
	{
		i = scanf("%d", &arr[size]);
		k = getchar();
		++size;
		printf ("%d:%d ", i, k);
	}
	printf ("\n%d\n",size);

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

　　测试数据（控制台输入的话就变成输入一行然后一个回车键，可以把所有内容存到txt中然后重定向）：

1,2,3,4,5,6,7,8,9,10 
11,12,13,14,15,16,17,18,19,20 
21,22,23,24,25,26,27,28,29,30
