c++ rainbow text

To create rainbow text in C++, you can use escape sequences to change the color of the text output. Here's an example with explanations for each step:

Step 1: Include the necessary header file.

#include <iostream>

This line includes the iostream library, which allows us to use standard input/output streams like cout.

Step 2: Define the main function.

int main() {
    // Your code here
    return 0;
}

This is the main entry point of the program. All the code for the rainbow text will go inside this function.

Step 3: Use escape sequences to change the text color.

std::cout << "\033[31mR\033[32mA\033[33mI\033[34mN\033[35mB\033[36mO\033[37mW\033[0m";

In this line, we use escape sequences to change the color of each letter in the word "RAINBOW". Here's how it works:

  • \033[ is the escape sequence to start color formatting.
  • The numbers 31, 32, 33, 34, 35, 36, 37 represent different color codes for red, green, yellow, blue, magenta, cyan, and white respectively.
  • Each letter is followed by the appropriate color code, enclosed in \033[ and m.
  • \033[0m resets the color back to the default.

Step 4: End the line.

std::cout << std::endl;

This line adds a new line after the rainbow text to separate it from the following output.

Step 5: Return from the main function.

return 0;

This line returns 0 to indicate successful execution of the program.

That's it! When you run the program, it will display the word "RAINBOW" in different colors, creating a rainbow effect.
