CONCEPT OF \n

 #include <stdio.h>

int main() {

    printf("First line\n");

    printf("Second line\n");

    printf("Third line\n");

    return 0;

}

Output:

arduino

Copy code

First line

Second line

Third line

👉 Explanation:

"First line\n" → prints First line then moves to the next line.

"Second line\n" → prints Second line then moves to the next line.

"Third line\n" → prints Third line then moves to the next line.

So every time you put \n at the end, the cursor moves down one line after printing the text.

-----------------------------------------------------------------------------------------------------------------------------

📌 Example 1: \n at the end

#include <stdio.h>
int main() {
    printf("Hello World\n");
    printf("This is C programming\n");
    return 0;
}

Output:

Hello World
This is C programming

👉 Here \n moves the cursor to the next line after the text.

---

📌 Example 2: \n at the beginning

#include <stdio.h>
int main() {
    printf("\nHello World");
    printf("\nThis is C programming");
    return 0;
}

Output:

Hello World
This is C programming

👉 Because \n is written before the text, the cursor first jumps to a new line and then prints.

📌 Example 3: \n in the middle

#include <stdio.h>
int main() {
    printf("Hello\nWorld\nin C\nProgramming");
    return 0;
}

Output:

Hello
World
in C
Programming

👉 Here, \n splits the text into multiple lines wherever it appears in the middle.

---

✅ Summary:

• \n = moves to a new line.

• At end → text prints then moves to next line.

• At beginning → first moves to next line, then prints text.

• In middle → splits the output into multiple lines.
