How to get Length of String in C ?

Answer

To get the length of a given string in C, you can use the strlen() function from the library.

✐ Examples

1 Length of "Hello World" String

In this example,

We include the and header files.
We create a character array named str1 with a string value of "Hello World".
We then use the strlen() function to get the length of the string and store the returned value in the variable length1.
Finally, we print the value in length1 to the console using printf() function.

C Program

// Length of "Hello World" String
#include <stdio.h>
#include <string.h>

int main() {
    char str1[] = "Hello World";
    int length1 = strlen(str1);
    printf("Length of given string is: %d\n", length1);
    return 0;
}

Output

Length of given string is: 11

2 Length of "apple" String

In this example,

We include the and header files.
We create a character array named str2 with a string value of "apple".
We then use the strlen() function to get the length of the string and store the returned value in the variable length2.
Finally, we print the value in length2 to the console using printf() function.

C Program

// Length of "apple" String
#include <stdio.h>
#include <string.h>

int main() {
    char str2[] = "apple";
    int length2 = strlen(str2);
    printf("Length of given string is: %d\n", length2);
    return 0;
}

Output

Length of given string is: 5
