What error is program snippet giving?

Why is the program snippet giving error?

your compiler should tell you.
but the 'main' issue is this kinda thing:

int n;
	std::cout << "Enter the no. of inputs:- ";
	std::cin >> n;
	std::string str[n];

c-style array needs a constant expression. do you have to use c-style arrays?

gets(...) does not take a string. Use getline(...) instead:
