QString provides many functions for converting numbers into strings and strings into numbers. See the arg() functions, the setNum() functions, the number() static functions, and the toInt(), toDouble(), and similar functions. To get an upper- or lowercase version of a string use toUpper...
cout << str << endl; } 在循环操作字符串时,必须小心不要松开字符串中的位置。换句话说,在删除元素时,如果不更正迭代器,每次都会跳过字符。 Sidenote:最好使用STL函数(正如注释中所指出的。类似这样的问题也是为什么要使用std-functions)的突出例子。
The STL string class also provides many methods of string assignment. String class functions: Constructors: 1 string sVar1("abc"); 2 string sVar2(C-string-variable); // Null terminated char 3 string sVar3(10," "); // Generate string initialized to 10 blanks. 4 string sVar4(Var1...
With STL, on the other hand, you have to explicitly call c_str. This is really nit-picking and some would even argue it's better to know when you're performing a conversion. For example, CStrings can get you in trouble with functions that use C-style variable arguments (varargs), ...
QStringList provides several functions allowing you to manipulate the contents of a list. You can concatenate all the strings in a string list into a single string (with an optional separator) using the join() function. For example: QString str = fonts.join(", "); // str == "Arial,...
