Pointers and Character Strings

Strings in C are arrays of characters terminated by a null character ‘\0’.

• You can use pointers to access and manipulate strings.
• Pointer arithmetic helps traverse strings character by character.
• A string literal can be assigned to a char * pointer.
• Dereferencing and pointer arithmetic allow access to each character.

Example:

#include <stdio.h>

int main() {
    char str[] = "Hello";
    char *ptr = str;

    while (*ptr != '\0') {
        printf("%c ", *ptr);
        ptr++;
    }
    printf("\n");

    return 0;
}
