Introduction to Strings in C Programming
Strings in C programming are used to store and manipulate text. A string is a collection of characters ending with a null character \0.
Understanding strings in C programming is important for handling text data such as names, messages, and inputs.
What is a String in C Programming
A string is an array of characters terminated by a null character.
Syntax of String Declaration
Example
Initialization of Strings in C Programming
Method 1: Using Character Array
Method 2: Using String Literal
Input and Output of Strings
Using scanf()
int main() {
char name[20];
printf(“Enter your name: “);
scanf(“%s”, name);
printf(“Name: %s”, name);
return 0;
}
Using gets() and puts()
int main() {
char name[20];
gets(name);
puts(name);
return 0;
}
Accessing Characters in String
Each character in a string can be accessed using index.
int main() {
char str[] = “C”;
printf(“%c”, str[0]);
return 0;
}
Example: Print String Using Loop
int main() {
char str[] = “Hello”;
int i;
for(i = 0; str[i] != ‘\0’; i++) {
printf(“%c\n”, str[i]);
}
return 0;
}
