Then why not use numeric datatypes than string?

sscanf should do the trick no?

You first have to convert it to an integer (how to do it depends on what you mean by "string" exactly), increment the integer and then convert it back to a string.

Well, it's simple:

Convert the string to a numeric value.
Increment the numeric value
Convert back the numeric value to string

What are your troubles in doing that? :) Too slow Carlo, too slow... :rolleyes:

Why can you not just use an integer instead of exploring ways to misuse a string?

i like it. 8 bits for each digit instead of 1/ln(|digit|). how many times are you incrementing?

Well, exporing double roundings is even more fun... :rolleyes:

I can not define that variable as int as i would need to store the variable value in txt file using CStdioFile. Using this class, it does not allow to store "int" value. *********** EXAMPLE **************** int m_barNo; cfile.WriteString(m_barNo); **************************************** if i try to store the int value using WriteString member function of CStdioFile, it gives an error as below "error C2664: 'WriteString' : cannot convert parameter 1 from 'int' to 'const char *' " Hence i would need to increment string..could anyone suggest how do i proceed...
