C: Writing Your First Program

Let's use C's standard input and output to print a greeting to the screen.

💻 Hello World Example

#include <stdio.h>

int main() {
    // Print a string to the console
    printf("Hello, C Language Learning Center!\n");
    return 0;
}

🔍 Code Detailed Explanation

1. #include <stdio.h>

   • This is the Standard Input/Output header file. It must be included to use standard input/output functions like printf.

2. int main()

   • This is the entry point of the program. Every C program must start execution from the main function.

3. printf(...)

   • A function used to print formatted strings. \n represents a newline character.

4. return 0;

   • A signal to the operating system indicating that the program has terminated successfully.
