Help With Converting Digits Or Symbols Into Numbers

[Tomdub]

Hey all,

I'm a little confused on the proper method for converting symbols and what not into numbers.

For example, writing a program that reads from a file.

Say the file has input: $7,5,21%!87,9!8.32

I'd want the output to be on 3 separate lines as;

7521
879
832

So far this is the code I have below:

int main()
{
char ch;
ifstream inFile;
ofstream outFile;

infile.open ("Sample.txt");
if (not inFile)
{
cout<<"failure to open sample.txt"<<endl;
system("Pause");
return 1;
}
outFile.open("out.txt");
if(not outFile)
{
cout<<"Failture to open out.txt"<<endl;
system("pause");
return 1;
}

inFile.get(ch);
while(inFile)
{
while((ch!= '\n') and inFile)
    {
     outFile.put(ch);
     inFile.get(ch);
    }
if (inFile)
{
outFile.put(ch);
inFile.get(ch);
}
}
system("pause");
inFile.close(); outFile.close();
return 0;

}
