H:\finalproject.cpp(14) : warning C4305: 'initializing' : truncation from 'const double' to 'float'

This means that symbolic constants (like 12.99) are doubles but your variable is a float. You are being warned that the value in the double may lose accuracy when converted to a float. Recommendation: Never use float. Stick with double unless you can bwrite down on paper the technical reason why it has to be a float.

H:\finalproject .cpp(38) : error C2065: 'choice' : undeclared identifier

Here you refer to a variable (choice) that you have never defined.

H:\finalproject .cpp(45) : error C2447: missing function header (old-style formal list?)

Your braces are out of balance. Be sure you have matching {} pairs.

H:\finalproject .cpp(58) : error C2001: newline in constant

Here a constant is missing a ".

H:\finalproject .cpp(130) : error C2447: missing function header (old-style formal list?)

Again your braces are out of balance.

Te exact line number where the compiler got into trouble is in the error.

sorry to ask another question, but to be specific, what should i do exactly? im not really good with this programming thing and i would greatly appreciate specifically what to do :)

[weaknessforcats]

Change your float variables to double.

Verify every one of you { has a matching }. Remember, this error can make a function look like it is written inside another function:

void Function1()
{
<-------------missing }
void Function2()
{
 
}

Make sure every " has a matching " on the same line:

cout << "hello
            world!";

should be:

cout << "Hello"
            " world";

or

cout << "Hello world";

In any case, the procedure is to fix the first error/warning and then rebuild. Then fix the first error again. Often later errrors are the result of previous errors.

[qwert7465]

i did what you said about the " and the matching " but the part with { and the matching }, i cant find where to put the other one. when i put in another one after my int main() i get a ton of errors requiring ;.

You have to go thriugh the code carefully and make sure your {} are paired up correctly.

Here's the first problem:

int main() 
{ 
    do 
    { start_or_startover(); } 
    while (choice == 10); 
 
    receipt(); 
 
    return 0; 
}     <<<<<<<<< end of main()
 
{     <<<<<<<<<<<<what's this for?
    cout << "Ferger's Technology Store" << endl << endl;
