creating a string using the values of variables

[locus]

I am trying to create a string with the values of some variables as follows

const char *quer = "insert into comm_records (caller_id,userID,c_area,c_duration,c_date) values ('"+number+"','"+userID+"','"+area+"','"+duration+ "','"+date+"')";

all the identifiers between the + signs are variables, and i am trying to form a string with the valuse of those variables. i keep getting the following error

: error C2110: '+' : cannot add two pointers

non of the variables are pointers, some are integers and some are strings, could someone give me some pointers on how to achieve what i want to do.

Thanks.

May be not but all you string constants are.

You can not concatenate strings and string constants in this way in C. You should either, declare a character array and you sprintf to fill in the required contents (but you will need to be able to predict what size it will need to be. Or declare a variable of type string and add all the various parts to it.
