Output string type in C

In C, you can use the following method to output string type :

• std::cout Object:

  • std::cout << string_variable

• Output operator (<<):

  • string_variable << std:: cout

##Example:

#include <iostream>
#include <string>

using namespace std;

int main() {
  string my_string = "Hello, C++!";

  // 使用 std::cout 对象输出
  cout << my_string << endl;

  // 使用输出运算符输出
  my_string << cout << endl;

  return 0;
}

Output:

<code>Hello, C++!
Hello, C++!</code>

Note:

The two methods are essentially equivalent, but it is more common to use
• std::cout object output. The
• endl manipulator can be used for line breaks.
