    strlen()

    Could you give me a example code to get first 3 letters of a string by using strlen().Thanks.

    Such as like this, no details just a small example.
    Code:
        
    int strlen ( char * string ) ;
    
    printf ( "%d", strlen( "HelloMum" )) ;
    
    Output is 13

    do you know what strlen is for? It's for finding the length of a string. If you only need the first 3 characters, you don't need strlen.

    I looked at the behavior of strncpy() and if the string it's copying is longer than the number of bytes you tell it to copy, it doesn't null-terminate the result. So you need to define a buffer array of 4 chars, and set the last element to '\0' before using strncpy().
