RE: [Dev-C++] Using Command Line to Execute program

[<Ech...@ne...>]

I assume you mean to compile it, and that the program is in a file called harmonic.c

Since dev-cpp uses gcc as it's compiler, I think you would youise the following command, from the file's directory:

gcc harmonic.c -o harmonic.exe

however, since it is a windows compiler, it might need other options? :-)

---- message follows ----

Please show me step-by-step how to use DevC++ to run a program through 
Command Line method fpr the following program. Thank you!!!!!!!!!!!!!!


#include  <iostream.h>
#include  <stdlib.h>
#include <stdio.h>
               
//----------------------------------------------------------------------------

----
// array passed as pointer

float  sum_array( float *A, int len )
{
   float s = 0;
   for( int i = 0; i < len; ++i )
   s += A[i];
   return s;
}

// array passed as array of unspecified length

float  average_array( float A[], int len )
{
   return  sum_array( A, len )/len;
}

//----------------------------------------------------------------------------

----
void  main( int argc, char **argv )
{
   if( argc != 1 )
   {
       cerr << "Usage: " << argv[0] << " number" << endl;
       cerr <<"int argc: "<<argc;
       getchar();
       exit(0);
   }

   int  n = atoi( argv[1] );
   
   float  H[n];
   
   for( int i = 1; i <= n; ++i )
   H[i-1] = 1/float(i);
   
   cout << "harmonic number " << n << ":   " << sum_array( H, n ) << endl;
   cout << "average 1/i up to " << n << ": " << average_array( H, n ) << 
endl;
   
   exit(0);
}
