今日份练习

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

void Reverse(int arr[], int sz)
{
	int left = 0;
	int right = sz - 1;
	while (left < right)
	{
		int tmp = 0;
		tmp= arr[left];
		arr[left] = arr[right];
		arr[right] = tmp;
		left++;
		right--;
	}
}

int main()
{
	int arr[10] = { 1,2,3,4,5,6,7,8,9,10 };
	int sz = sizeof(arr) / sizeof(arr[0]);
	Print(arr, sz);
	Reverse(arr, sz);
	Print(arr, sz);
	return 0;
}


//2.数组交换
#include<stdio.h>
int main()
{
	int arr1[] = { 1,3,5,7,9 };
	int arr2[] = { 2,4,6,8,0 };
	int tmp = 0;
	int i = 0;
	int sz = sizeof(arr1) / sizeof(arr1[0]);
	for (i = 0; i < sz; i++)
	{
		tmp = arr1[i];
		arr1[i] = arr2[i];
		arr2[i] = tmp;
	}
	return 0;
}
