Now, we want to get the last character e from the above string. Getting the last character To access the last character of a string in C, we first need to find the last character index using the strlen(str)-1 and pass it to the [] notation. The strlen() function returns the total...
STL的C++标准程序库中的string类,使用时不必担心内存是否充足、字符串长度等问题,并且C++中的string类作为一个类,其中集成的操作函数(方法)足以完成多数情况下的程序需求,比如说string对象可以用"="进行赋值,使用"=="进行等值比较,使用"+"进行串联。 如果要使用C++的string类必须包含头文件,并引入命名空间: 1 #inc...

String类包含用于连接两个字符串的方法: string1.concat (string2相等); 这将返回一个新的字符串,它是string1,末尾添加了string2。 字符串通常与+运算符连接,如in“Hello”+“world”+“! 需要注意的是:当使用字符串的时候,如果超过行大小,则需要+连接比如如下: AI检测代码解析 String quote = "Now is the...
