Porting c++ from windows to Linux
I have some old code that figures out Qfactors for me, now I need help on porting it over to Linus to do some speed test on the Linus computers.
I been deep in FoxPro 5 for the last year ( the pain!) and now starting this little project.
Here is the code if you would please point out the place that need to change.
Code:
#include <stdio.h>
#include <time.h>
// basic file operations
#include <iostream>
#include <fstream>
// using namespace std;
int y;
double z;
void print(const int *v, const int size, ostream &outfile)
{
y=y+1;
if (y == 1000000) {
printf ("%15.0f\n",z);
y=0;
}
if (v != 0) {
for (int i = 0; i < size; i++) {
outfile << v[i];
outfile << ",";
}
outfile.setf(ios::fixed,ios::floatfield);
outfile << z;
outfile << "\n";
z=z+1;
}
} // print
void visit(int *Value, int N, int k, ostream &ofile)
{
static level = -1;
level = level+1;
Value[k] = level;
if (level == N)
print(Value, N, ofile);
else
for (int i = 0; i < N; i++)
if (Value[i] == 0)
visit(Value, N, i, ofile);
level = level-1; Value[k] = 0;
}
main()
{
const int N = 16 ;
int Value[N];
time_t t;
time_t t1;
z = 1;
t = time(0);
double dif;
ofstream myfile;
myfile.open ("16Count.txt",ios::app);
myfile.setf(0,ios::floatfield); // floatfield not set
myfile.precision(0);
printf("Start time is %s", ctime(&t));
myfile << "Start time is ";
myfile << ctime(&t);
myfile << "\n";
for (int i = 0; i < N; i++) {
Value[i] = 0;
}
visit(Value, N, 0, myfile);
t1 = time(0);
printf("End P1 time is %s", ctime(&t1));
myfile << "End P1 time is %s";
dif = difftime(t1,t);
printf("End time is %.2lf.\n ", dif);
myfile << dif;
myfile << "/n";
myfile.close();
printf("Push any key to exit.\n ");
return 0;
}
