    Save a file with a name in a variable?

    Hi, i need to know how to do something that might be really easy, but i just don't know how.
    The thing is that i open a file allocated, for example in," C:\example " and i need to save it in another path such as " C:\example\folder"

    But when i open the file it has a previous name (zippeddata.txt), and in the program i ask the user to enter a name to save the modified file, in the new path.

    The thing is that i cant make it work when the user writes the new name of the file, i dont know the code to do that.

    #include <stdio.h>
    main() {
    FILE *original, *copy;
    char c, name[20];
    original = fopen ("C:\\example\\zippedData", "r");
    printf ("File name?"); //Input name to save the file//
    scanf ("%s",name);
    printf ("%s\n", name);
    copy = fopen ("C:\\example\\folder\\ *** I DON'T  KNOW WHAT GOES HERE *** .txt","w"); //Creates new file, which must have the "name" variable//
    while ((c = getc(original)) != EOF)
    if (c != ';')
    putc(c, copy);
    else putc (',', copy);
    fclose (original);
    fclose (copy);
    return 0;
    Please Help!!

    Im sorry if my English it's not so good... it's not my native language

    You could use strcat to concatenate two strings together.

    You might want something like this:
    char copyname[300];
    sprintf(copyname, "C:\\example\\folder\\%s.txt", name);
    copy = fopen(copyname,"w");
