* The functions toUpperCase and toLowerCase return a new string whose * characters appear in the desired case. These implementations rely on * the fact that the characters in the string are copied when the * argument is passed to the function, which makes it possible to change * the case ...
[root@localhost cpp_src]# g++test.cpp [root@localhost cpp_src]# ./a.outaaa bbb ccc ddd//输入aaa bbb ccc ddd按下换行aaa bbb ccc ddd//直接输入换行//直接输入换行12345//输入12345 按下换行12345 这里需要注意的是: getline不会忽略一行开头的换行符,而且输入后在string对象最后不会加上endl换行符。
cin.getline() Example in C++In this program will read details name, address, about of a person and print in different lines, name will contain spaces and dot, address will contain space, commas, and other special characters, same about will also contains mixed characters. We will read all ...
In this article, we will learn how to write a C++ program to check if two strings match where one string contains wildcard characters. Wildcard characters are those that can be compared with one or more characters. ‘*’ and ‘?’ are typical wildcard characters where ‘*’ can be compa...

In the above program, we have an STL vector myNumbers of type string. Next, we add elements to this vector using the push_back method and then display each of the elements of the vector. If we see the entire working of the STL vector and array of strings, we see that in this case...
