how to print text on C++
To print text in C++, you can use the cout
object from the iostream
library. Here's how you can do it, step by step:
- Include the necessary header file:
#include <iostream>
This line includes the iostream
header file, which contains the definition of cout
and other related objects.
- Use the
cout
object to print the text:
std::cout << "Hello, World!";
This line uses the <<
operator to send the text "Hello, World!" to cout
, which represents the standard output stream. The std::
prefix is used to specify that cout
is part of the std
namespace.
- End the line (optional):
std::cout << "Hello, World!" << std::endl;
You can use << std::endl
to end the line and move the cursor to the next line. This is optional, but it's commonly used to print each output on a new line.
- Compile and run the program:
Save the file with a
.cpp
extension, such asmain.cpp
. Then, compile and run the program using a C++ compiler.
Here's the complete code example:
#include <iostream>
int main() {
std::cout << "Hello, World!" << std::endl;
return 0;
}
This code includes the iostream
header file, defines the main
function, and uses cout
to print the text "Hello, World!" followed by a new line.
When you run the program, you should see the output "Hello, World!" printed on the console.
