hi how write this in c++?, could i use <fstream>
this it´s ok, (c and gnuplot)
/******/
#include <stdio.h>
#include <stdlib.h>
#define GNUPLOT_PATH "D:/instaladores/gnuplot/gnuplot/bin/pgnuplot"
int main (int argc, const char * argv[]) {
FILE *gp;
gp = popen(GNUPLOT_PATH, "w");
if(gp == NULL){
fprintf(stderr, "Oops, I can't find %s.", GNUPLOT_PATH);
exit(EXIT_FAILURE);
}
//fprintf(gp, "set term aqua title \"Function A\" \n");
fprintf(gp, "set samples 2048 \n");
fprintf(gp, "plot [-512:512] -abs(x*sin(sqrt(abs(x))))+400\n");
fflush(gp);
getchar();
pclose(gp);
return(EXIT_SUCCESS);
}
/**************/
i have a problem here:
/**************/
#include <cstdlib>
#include <fstream>
#include <iostream>
#define GNUPLOT_PATH "D:/instaladores/gnuplot/gnuplot/bin/pgnuplot"
using namespace std;
int main()
{
fstream fSalida;
fSalida.open(GNUPLOT_PATH,ios::out|ios::app );
//¿¿¿ :-)
// cout<<fSalida<<"set samples 2048"<<endl;
// cout<<fSalida<<"plot [-512:512] -abs(x*sin(sqrt(abs(x))))+400"<<endl;;
system("PAUSE");
return EXIT_SUCCESS;
}
