How to Check if String ends with Specific Suffix in C ?

Answer

To check if a string ends with a specific suffix in C, you can use the strstr() function from the C Standard Library.

✐ Examples

1 Check if "Hello World" ends with suffix "World"

In this example,

We include the string.h header file to use the strstr() function.
We create a variable named str1 with a string value of "Hello World".
We then use the strstr() function to find the occurrence of the suffix "World" within the string str1.
If the suffix is found at the end of the string, the function returns a pointer to the last occurrence of the substring; otherwise, it returns NULL.
Finally, we check if the returned pointer is not NULL to determine if the string ends with the specified suffix and print the result to the console.

C Program

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

int main() {
    char str1[] = "Hello World";
    char* suffix = "World";
    char* result = strstr(str1, suffix);
    if (result && result == str1 + strlen(str1) - strlen(suffix)) {
        printf("String ends with suffix 'World': true\n");
    } else {
        printf("String ends with suffix 'World': false\n");
    }
    return 0;
}

Output

String ends with suffix 'World': true

2 Check if "apple" ends with suffix "banana"

In this example,

We include the string.h header file to use the strstr() function.
We create a variable named str2 with a string value of "apple".
We then use the strstr() function to find the occurrence of the suffix "banana" within the string str2.
Since the suffix is not found, the function returns NULL.
Finally, we print the result to the console.

C Program

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

int main() {
    char str2[] = "apple";
    char* suffix = "banana";
    char* result = strstr(str2, suffix);
    if (result && result == str2 + strlen(str2) - strlen(suffix)) {
        printf("String ends with suffix 'banana': true\n");
    } else {
        printf("String ends with suffix 'banana': false\n");
    }
    return 0;
}

Output

String ends with suffix 'banana': false
