problems with my program again!

[begum]

hello everyone!
my program is not working properly,
it is not summing the values that i entered.
It should take the double values and add them and also take strings and
makes the * as a multiplacation .

thanks !!!

here is my program

if(language=='E ' ||language=='e' )
{
cout<<"Enter prices or <S>top:";

}
else if(language=='T '||language=='t ')

}

Ever heard of a debugger? Step through the program and see what it's doing.

Or add cout statements at key points to report whether you reach certain
points and what values exist at those points, to see where things are going
right/wrong.

I see that you define:

char s;

Then later you have:

cout<<"Enter prices or <S>top:";
cin>>s;

So all that can be entered is a single char. How is the user supposed
to enter any prices, if he can enter only a single char?

char temp[MAX_INPUT_SIZE]; //input,
char array; //en basta hepsi NULL'a esit
char part1[MAX_INPUT_SIZE], part2[MAX_INPUT_SIZE];

These variables are never initialized or read in.
Also, it is a bad idea to have a variable named "array" that is not an
array.
