plodata<<

I am writing data to a file but want to include an integer (i) in the title of the file. How can I go about this?

i = 0, 1, 2...

ofstream plotdata("../Data/supersonic_jet(i).vtk", ios::out);

filename:

supersonic_jet0.vtk
supersonic_jet1.vtk
supersonic_jet2.vtk
etc

Use a stringstream to build the filename.

can you give me an example please?

Say i want to name the file name after string s. How do I go about this?

string s = "file1.vtk"

ofstream plotdata("../Data/(s)", ios:out);

One possible way:

Code:

---

string s = "file1.vtk";
ofstream plotdata( ("../Data/"+s).c_str() );

---

Cheers
