数据结构表的查找c语言代码

数据结构中常用的表格查找算法包括顺序查找和二分查找，以下是它们的C语言代码实现：

1. 顺序查找

int Sequential_Search(int *a, int n, int key)
{
    int i;
    for (i = 0; i < n; i++)
    {
        if (a[i] == key)
            return i;
    }
    return -1;
}

2. 二分查找

int Binary_Search(int *a, int n, int key)
{
    int low, high, mid;
    low = 0;
    high = n - 1;
    while (low <= high)
    {
        mid = (low + high) / 2;
        if (a[mid] == key)
            return mid;
        else if (a[mid] > key)
            high = mid - 1;
        else
            low = mid + 1;
    }
    return -1;
}
