accessing characters in a stringString strings can also be used to access each of these characters in the same way as a string array. The starting subscript for string strings is still starting at 0. Take a look at the following code:#include

The reason for discarding the char* string is to choose the string class in the C + + standard library because he does not have to worry about the adequacy of the memory, the length of the string, and so on, and as a class, his integrated operation

The c++11 supports range-based for loops. This is a very convenient feature that can save a lot of code. The following code makes it easy to traverse the elements in the vector and print them out: 12345678 std::vectorint>
