Re: [Dev-C++] how to draw a graph in a .xls file with C++

[Eric <eri...@cl...>]

As Alfred said ".XLS is a formatted file" 

Is this homework to a C++ class?
you say "built  a graph"  and  "using the two columns"

I think what is the mathematics function of the graph? e.g. just a simple  x=y+1.
I am sure a graph needs more than "two columns" 



man what a weird project.

In the following simple program I have to write the code to built  a graph in
the .xls output file using the two columns that have been created.

Thanks,
George


#include <fstream> 

using namespace std; 



int main() 

{

    double a[10]= {1,2,3,4,5,6,7,8,9,10};

    double b[10]= {11,12,13,14,15,16,17,18,19,20}; 

                        

ofstream fout; 

fout.open("www.xls"); 

    int n= 0;

for(n= 0; n< 10; n++)

{

   fout<< a[n]<<"\t"<<b[n]<<endl;

    } 

fout.close(); 

    return 0;

}
