#include <stdio.h>
#include <string.h>
int main()
{
    //file pointer
    FILE *fp = NULL;
    //Message
    char * message = "I love Aticleworld.com";
    //Variable for message length
    int length = 0;
    //create and open the texr file
    fp = fopen("aticleworld.txt", "w");
    if(fp == NULL)
    {
        printf("Error in creating the file\n");
        exit(1);
    }
    //Get the length of message
    length = strlen(message);
    //write the length in file
    fprintf(fp,"%d",length);
    //write the message in file
    fprintf(fp,"%s",message);
    //Close the file
    fclose(fp);
    return 0;
}

Output:

In the below image, you can see the fprintf write the 22 (message length) in string format, so it is showing as it as 22.
