HI guys,
I am using c-free 4.0 IDE and trying to compile .cpp files in cpp/src/. I am getting error when i complile these 3 files-->

1.) dataanalysis.cpp (3 errors and are all same): ERROR::no matching function for call to basic_string<char,string_char_traits<char>, __default_alloc_template<false,0> >::clear()
ove
2.interpolation.cpp(1 error) same as above (line 7992)

3.alglibmisc.cpp( 1error) same as above line 480.

all the above error are generated due to this function ---> "s_out.clear()";
PLease help.. Its really urgent..

If u want to try c-free 4.0(for debugging) u can use link "http://www.programarts.com/cfree_en/download.htm" (=7MB) (4.0 VERSION)

What compiler you used? It complains about std::string.clear(), but this method is pretty standard and should be present in all modern standard C++ libraries.

mingW2.95 compiler

I also have another query..In c-free 4.0, I included only ap.cpp and the header file ap.h (just to learn about real_2d_array objects).
But there is one last problem..

I have a double datatype array say a[2][2] and want to copy its contents to real_2d_array object say b.

I took a double pointer (*p=NULL)and did p=b[0] so that I may store value in b via p and increment it by 1.. i.e

*(p+0xi)+j=a[i][j]; but its not working.

I tried simple equating b[0][0]=a[0][0] but when we execute, it says <filename>.exe has stopped working..
Any help is greatly appreciated..

Program--->

#include<iostream>
#include<conio.h>
#include<stdio.h>
#include<math.h>
#include "ap.cpp"
#include<ap.h>
int main()
{
using namespace::alglib;
real_2d_array b;
double a[2][2]={{0.99,0.99},{1.00,1.00}};
b[0][0]=a[0][0];
cout<<b[0][0];
getch();
return(0);
}
