问题：把一个字符串转成一个整数。思路：其实，这道题考的不是怎么去把一个数转成一个整数，而是考你是否能够把所有的情况都考虑完全，我们应该考虑的因素如下：1. 这个字符串是否为空。2. 这个字符串是否有非

However, there is a big difference between the two, which will lead to different porting code functions. I thought of finding a method on the Internet to write the same functions as atoi in Java, but I couldn't find it, so I simply wrote one with my understanding of atoi.

We use atoi to convert a numeric string to his integer value. atoi is a c library function and it takes a string as an argument and returns its integer value. In this article, we will see the atoi implementation in c and its important features.

Implement atoi which converts a string to an integer.. The function first discards as many whitespace characters as necessary until the first non-whitespace character is found. Then, starting from this character, takes an optional initial plus or minus sign followed by as many numerical digits as possible, and interprets them as a numerical value.
