Question

How to take some unknown number of integers from input and display them on the console?

The number of values will be given through console.

Answer 1

Well the prototype for main is:
main(void) or
main(int argc, char *argv[]);

This are the command line arguments of the program
you can iterate through them with something along this lines

  int i = 0;
    for (i=0; i < argc; i++) {
         printf("%s" argv[i]);
}

Untested but should be enough to get you going.
