c++ in turbo c++~

Hey hey, once again I am calling out for help.

Okay, I have a few of the same errors and I have no clue how to fix it.

Part of the code is:

printf("Customer Number : %s\n",customer_number.c_str());
printf("Customer Name : %s%s\n",customer_initial.c_str(),customer_surname.c_str());
printf("Customer Address : %s %s %s %s %s%s\n\n",street_number.c_str(),street_name.c_str(),street_type.c_str(),
suburb.c_str(),state.c_str(),postcode.c_str());


My error message:
Structure required on left side of . or .* in function main()

--------------------------------
I need help :(
