3.4、String operations 字符串操作 字符串操作,主要操作有返回字符串指针、查找、拷贝、获得子串等。(这里就使用其中的一部分)。 1、c_str* c_str返回string对象里的字符串指针。(需要注意的就是返回的指针是const修饰的,必须用const指针接受)。 void test9(){string s1("Hello World");const char* s = s1...

it’s so important and useful, C# language syntax was added in C# 6 to make it even more usable. This “string interpolation” functionality enables developers to place a$character just before the string; then, rather than specifying arguments for the format...
How to Get More Control When Performing String Operations In addition to the new secure string functions, the C run-time library has some new functions that provide more control when performing string manipulations. For example, you can control the filler values or how truncation is performed. Na...

match("[abc]","apple");returns1, because it matches the a in "apple." match("[abc]","kiwi");returns0, because "kiwi" doesn't contain an a, b, or c. match("gr[ae]y","grey");returns 1. This expression also matches "gray." ...
You can index into, reshape, and concatenate string arrays using standard array operations, and you can append text to them using the+operator. If a string array represents numbers, then you can convert it to a numeric array using thedoublefunction. ...
The Compare(String, Int32, String, Int32, Int32, CultureInfo, CompareOptions) method is designed primarily for use in sorting or alphabetizing operations. It should not be used when the primary purpose of the method call is to determine whether two substrings are equivalent (that is, when ...
In c, an assignment from the third character of b to the second character of a can be written as a[1] = b[2];. On a machine with character-sized memory operations (cload and cstore), this translates into the simple code shown in the margin. (Recall that the first character in a...
C++ has got the concept of overloading which makes an operator perform other operations apart from the basic or default operation. Initially, we create a new empty string. We use the overloaded '=' operator to store the data items character by character into the newly created empty string. ...
