How to get Last N Characters in String in C ?

Answer

To get the last N characters of a given string in C, you can use array indexing and string length.

✐ Examples

1 Last 5 Characters of "Hello World" String

In this example,

We create a character array named str1 with a string value of "Hello World".
We then calculate the length of the string using strlen() function and subtract 5 to get the index of the first character of the last 5 characters.
We copy the last 5 characters into a new character array last5Chars.
Finally, we print the last 5 characters.

C Program

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

int main() {
    char str1[] = "Hello World";
    int len = strlen(str1);
    char last5Chars[6];
    strcpy(last5Chars, str1 + len - 5);
    printf("Last 5 characters of the string are: %s\n", last5Chars);
    return 0;
}

Output

Last 5 characters of the string are: World

2 Last 3 Characters of "apple" String

In this example,

We create a character array named str2 with a string value of "apple".
We then calculate the length of the string using strlen() function and subtract 3 to get the index of the first character of the last 3 characters.
We copy the last 3 characters into a new character array last3Chars.
Finally, we print the last 3 characters.

C Program

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

int main() {
    char str2[] = "apple";
    int len = strlen(str2);
    char last3Chars[4];
    strcpy(last3Chars, str2 + len - 3);
    printf("Last 3 characters of the string are: %s\n", last3Chars);
    return 0;
}

Output

Last 3 characters of the string are: ple
