Answer 1

You may save your input as a file.(like "intput.txt"). Then call

freopen("intput.txt", "r", stdin);
//code to read from stdin.
fclose(stdin);

Answer 2

Put your data in a file then go to the project properties in Visual Studio and select the "Debugging" category.

In the "Command Arguments" property type:

< "path/to/the/file"

Now that file will be fed to the program via standard input when the debugger is launched or when you launch the program within Visual Studio (but without the debugger) using Ctrl-F5.

You can use VS macros to specify the project directory, etc. if you want the test file to move along with the project.
