Where each byte is a character in the string. The first byte being an ASCII '1', '2', etc. When you cast eachcharback to along, you are actually getting the ASCII value of each character in the string. So thechar'1' is actually represented in memory as an integer 49, '2' is '...
Now when you have a char that represents a ASCII/unicode digit (like '1'), and you subtract the smallest possible ASCII/unicode digit from it (e.g. '0'), then you'll be left with the digit's corresponding value (hence, 1) Because char is the same as short (although, an...

提要:本文从实现原理的角度上阐述和剖析了:在Java语言中,以String作为类型的变量在作为方法参数时所表现出的“非对象”的特性。 一、最开始的示例 写代码最重要的就是实践,不经过反复试验而得出的说辞只能说是凭空遐想罢了。所以,在本文中首先以一个简单示例来抛出核心话题: ...
void someFunc(char *someStr); 1. 再看这个函数调用: someFunc("I'm a string!"); 1. 把这两个东西组合起来,用最新的g++编译一下就会得到标题中的警告。 为什么呢?原来char *背后的含义是:给我个字符串,我要修改它。 而理论上,我们传给函数的字面常量是没法被修改的。
