What does this line of code mean?

[Thanase]

	for (int i = 0; i<5; i++)
		printf("arrayA[%d] = %d\n", i, arrayA[i]);

Line 2

And how can I replace this with a more simplified/less advanced form of code?

Seems fairly straight forward to me if you're using C. A C++ equivalent would normally utilize the standard output and stream operators.

cout << "arrayA[" << i << "] = " << arrayA[i] << endl;
