Strings in C (Simple Explanation for Beginners)

After learning arrays in C, the next important concept is strings.

Strings are used everywhere in names, messages, and text data.

Let’s understand them in a simple way.

---

What is a String?

A string is a collection of characters.

👉 In C, a string is actually an array of characters.

Example:

char name[] = "Ali";

---

How Strings Work in C

Every string ends with a special character:

👉 \0 (null character)

So internally, "Ali" is stored like this:

A  l  i  \0

---

Declaring a String

char str[10];

This means the string can store up to 9 characters + 1 null character.

---

Taking Input from User

#include <stdio.h>

int main() {
    char name[20];
    printf("Enter your name: ");
    scanf("%s", name);

    printf("Hello %s", name);
    return 0;
}

---

Displaying a String

printf("%s", name);

---

Important Points

• Strings are arrays of characters
• Always end with \0
• Use %s to print strings
• Be careful with size to avoid errors

---

Why Strings Are Important

Strings help you:

• Work with text data
• Take user input
• Build real-world programs

---

Final Thoughts

Strings are a key part of programming.

Once you understand strings, your programs will become more useful and interactive.
