String s1=”hello”与String s2=new String(“hello”)的区别: String类在内存中管理一个字符串常量池(常量池的一部分),池中所有相同的字符串常量被合并,只占用一个空间。 String s1=”hello”,先看池中有没有hello,没有就创建一个hello字符串对象。即采用此方法创建0或者1个对象。 String s2=new String(...

printf("Uppercase string: %s\n",str); return0; } In the above code, we first declare a character array called str with a size of 100. The user’s string is then read using thefgets()method. Thestrupr()method is then used to transform the string to uppercase. Thestrupr()method rec...
字符串类型,即string类型,因为使用方便,不必担心内存问题,越界问题等等,还有在不太确定即将存入的字符串长度的时候使用是非常好的。本片中,将会对string类型的字符串和char类型的字符串对比使用讲解,作为随笔笔记,记录常用的用法,同时也会随着见识的增长随时更新 ...
std::cout << line << std::endl; // write s to the output } return 0; } Name: getline 这个函数接受两个參数:一个输入流对象和一个 string 对象。getline 函数从输入流的下一行读取,并保存读取的内容到不包含换行符。和输入操作符不一样的是,getline 并不忽略行开头的换行符。仅仅要 getline 遇到...
