Hi ppl can anyone tell me what this error means?
error C2601: 'meanData' : local function definitions are illegal

it happens when you try to define a function within a function, see
http://msdn2.microsoft .com/en-us/library/sba3hty9.aspx

e.g. I try to define function meandata() within function fg1()

int fg1()
{
     int meanData() { return 1; }
     int j=meanData();
     return j;
}

when I compile it using Visual C I get the error message
m.cpp(5) : error C2601: 'meanData' : local function definitions are illegal

define it outside fg1()

int meanData() { return 1; }

int fg1()
{
     int j=meanData();
     return j;
}
