I've been trying to write this program that is suppose to read in a text file manipulate in and give the following out put infact here is the question
Implement a program that uses a form-letter template to generate form letters. Your program should read in a form-letter template from a file. The form-letter template has "holes" in it that are to be filled in with user-entered values. The holes are represented by a pair of @ signs. For example, suppose this is read in from a form-letter template file:
Congratulations, @@! You've just won @@!
To collect, please send $100 to
And suppose the user enters these two values for the two @@ holes:
Raheel Azhar
a new house
Your program should then print this form letter:
Congratulations, Raheel Azhar! You've just won a new house!
To collect, please send $100 to
:mad:
this is what i have so far but all i get is compilation errors
#include <iostream>
#include <string>
using std::cout;
using std::cin;
class FormLetter
{
public:
string letterTemplate;
//private:
void generateLetter();
};
FormLetter::FormLetter(string fname)
{
letterTemplate = fname;
f.open("letterTemplate", ios::in);
f.close();
}
void generateLetter()
{
string input;
int count = 0;
++count;
while(count <4)
{
getline(letterTemplate,'@');
cout << "Enter insertion text: " << endl;
cin >> input << endl;
letterTemplate.insert(find_first_of '@', input);
generateLetter();
cout << letterTemplate << endl;
}
}
int main()
{
FormLetter formLetter1("letterTemplate.txt");
formLetter1.generateLetter();
return 0;
}
please help

What kinds of compile errors?
I imagine it complains about these lines:
using std::cout;
using std::cin;
try just "using std;" instead.
and you make a constructor like this:
FormLetter::FormLetter(string fname)
but it isn't in the class definition; try adding "FormLetter(string fname);" after "public:" in the FormLetter class.
void generateLetter()
needs to be like this:
void FormLetter::generateLetter()
and so on; the compiler should be pointing out the line number that has a problem and a general idea of what the problem is....

I think your question is about c++ ... so it should be posted in c++ forum ... you'll get replies there.

so thats why I am having a few headaches
i am also a new member to this site
so I appreciate any help i can get
Unless you HAVE TO use specific code, this works GR8!
(Sorry if its a little to late!)
Attached is the compiled exe in a zip file.

Cheese. In fact, I rather dislike cheese.

rogram for more than a couple days before you start teaching.

Alex Cavnar, aka alc6379
Come on, I was just trying to help. I have been programming in various languages for about three years, I am just new to C (I have been learning it for a month, but I got the compiler a week ago. I have known Dr Scheme for about nine months, PBasic for three years, and have used National Instruments Labview for two years.)
Besides, it works, doesn't it?
I know there is a better way to do it, but the way I described and compiled works.
I do understand, though, that my way does not fit the parameters set by the assignment. I will read more carefully next time. Although it completes the task, my program does not use files or forms. Sorry!

It is never safe, but it "works".
Sometimes the only way to capture someone's attention is to be a little bit of an ass. Try not to take it personally. Try to take it as constructive criticism without wiggle room.
