problem in input of values, never ending loop starts.

[kingfrz]

i made this first project, but there are some problems. Cant fix it.
The problem is that when I enter two words e.g "notes payable" in liability particulars input or "salaries expence" in expence particulars input a never ending loop starts. I think the problem is with space. Help me out with this plz.... and plz help me improve this more...it will be a great thank full

If you use cin>>, it will stop at whitespace. I recommend you change your char arrays to std::string's and use getline()

[kingfrz]

thanks zhuge....i did it, now the new problem is that it dosnt take the \n for enter.....means next function dosnt start unless 100 characters are given :(....

cin.getline(entry.particulars,100,'\n');

the \n is not exeptd... what can i do now :(
