Program: Writing a C Program to Display Your Name

In this section, we'll guide you through the process of writing a simple C program that displays your name. This exercise will help reinforce the basics of C programming and introduce you to the printf() function for output.

The Structure of the Program

Before diving into the code, let's recall the basic structure of a C program:

#include <stdio.h>

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

This structure includes the necessary header file (<stdio.h>) and the main function (main()), where the execution of your program begins.

Writing the Name Display Program

Now, let's create a program that prints your name to the console. Here's a simple example:

#include <stdio.h>

int main() {
    // Displaying your name
    printf("My name is [Your Name]\n");

    return 0;
}

Replace [Your Name] with your actual name. The printf() function is used to print text to the console, and represents a newline character, which adds a line break after displaying your name.

Getting Started

1. Open a Text Editor:

   • Choose a text editor of your preference (e.g., Notepad, Visual Studio Code, Sublime Text) to write your C code.

2. Create a New File:

   • Create a new file with a .c extension (e.g., display_name.c) to save your C code.

3. Write Your Code:

   • Copy and paste the provided C code into your file.

4. Save the File:

   • Save your file.

Compiling and Running Your Program

As mentioned in the previous sections, use the following steps to compile and run your program:

1. Open a Terminal or Command Prompt:

   • Navigate to the directory containing your C file using the cd command.

2. Compile the Code:

   • Use the following command to compile your code:

     gcc display_name.c -o display_name

3. Execute the Program:

   • On Linux:

     ./display_name

   • On Windows:

     display_name.exe

4. View the Output:

   • The console should display your name as per the printf() statement in your code.

Exploring Variations

Feel free to experiment with variations of the program. You can add additional information, change the formatting, or even prompt the user to enter their name using scanf() for interactive input.

#include <stdio.h>

int main() {
    char name[50];

    // Prompt user for name input
    printf("Enter your name: ");
    scanf("%s", name);

    // Displaying the entered name
    printf("Hello, %s!\n", name);

    return 0;
}

This variation prompts the user to enter their name, which is then displayed with a greeting.

Conclusion

Congratulations! You've successfully written a C program that displays your name. This simple exercise provides hands-on experience with basic input and output operations in C. As you progress in your C programming journey, you'll build on these fundamentals to create more complex and feature-rich applications.
