[Dev-C++] copying part of a string to another string?

[Calvin M. <cm...@pg...>]

Hello, I am trying to work an assignment for school, and I am having trouble
copying part of a string to another string.  the string is a area code that
includes the () and I am trying to get numbers only from it so I can turn
them into a int.  The code I have tried is below.  temp currently holds the
areacode withe the ().
Any input would be greatly appriceated.

for(i=1,x=0;i<4;i++)
{
   *areaptr = temp[i];
   areaptr++;
}
