string to int

[shan]

Hi to all,
Is there any way to convert string to integer.string will
contain only integers.I am using turbo c++
example :
"321" to 321

strtol() would be better, atoi() has poor error handling

The cast produces implementation-defined behavior if the return value
of strtol exceeds the representable range of int. Jack Klein has
written a very robust example of how to do this correctly at
http://home.att.net/~jackklein/c/code/strtol.html.

atoi(), or strtod(), or even sscanf().

That would be strtol(), surely.

strtol and related routines, or sscanf.
