    Join variable with string

    Hi,

    I'm trying to convert a C# program to a C version and I'm encountering all sorts of little problems. I try to solve them as a go along, but I can not figure out how to do the following:

    in C# I have (table_name is a string variable):

    string query = "SELECT * FROM " + table_name + " LIMIT 100";

    I would like to translate that line to C, but the support for strings is not that great. I have experimented with strcat and strcpy, but I can not get it to work. All help is welcome. Thanks.

    Look into something like sprintf.

    Hope is the first step on the road to disappointment.

    Thank you very much, sprintf did the trick.

    The solution for my problem was:

    char q[100];
    sprintf(q, "SELECT * FROM %s LIMIT 100", table_name);
