How to get the Last Character of a String in C

In this post, we're going to learn how you can get the last character of a string in C.

Unfortunately, C does not provide this functionality natively using some function, so we will have to rely on our code.

Thankfully, this isn't much of a challenge.

Getting the last character of a string in C

Remember that in C, a string is just an array of characters.

For our example, here is the string we're going to use:

CLIKE
char string[11] = "Hello World";

Therefore, the character we want to extra from this string is d.

To get the last character, we need to first get the index of that character.

We can use the built-in strlen() function to get the length of the entire string, then subtract 1 from it to get the index of the last character.

From there, we can just pass it to the string[index] syntax to get the last character.

CLIKE
#include <stdio.h>
#include <string.h>

int main() {
    char string[11] = "Hello World";
    
    int length = strlen(string);
    int index = length - 1;

    printf("Last: %c", string[index]);
}

This is the output:

BASH
Last: d

Conclusion

In this post, we learned how to get the last character of a string in C.

All you need to do is get the index of the last character, and use the string[index] bracket syntax to get the last character.
