So i have a piece of code that is creating 10 files. Currently it is hard coded so it creates the files "blah\folder\filename0", "blah\folder\filename1", etc.

makeFile(param1, "blah\\folder\\filename0", param3, param4);
makeFile(param1, "blah\\folder\\filename1", param3, param4);

Where the second param is "const char* name".

Ill have to remove the const from the parameter, but is there a way for me to change it so i can put into a for loop and specify the number of files i want created, then some how add the number onto the end of the name?

So something like

for(int i = 0; i < numFiles; i++
makeFile(param1, "blah\\folder\\filename"+(i as char), param3, param4);

Assuming C++, you can use std::stringstream to create a filename.

#include <sstream>

// ...

for(int i = 0; i < numFiles; i++)
std::stringstream stream;
stream << "blah\\folder\\filename" << i;
makeFile(param1, stream.str().c_str(), param3, param4);

For C, you could use sprintf().

There should be no need to remove the const on makeFile. const on a function parameter just means that the function is promising not to modify the value. The function can still be called on a non-const value.

Its giving me the following error:

error C2297: '<<' : illegal, right operand has type 'const char [24]'

Assuming that means stream cant take an array of chars using the <<
