[백준/BOJ/C++] 13297번 Quick Estimates

[문제]

Let’s face it... you are not that handy. When you need to make a major home repair, you often need to hire someone to help. When they come for the first visit, they make an estimate of the cost. Here they must be careful: if they overestimate the cost, it might scare you off, but if they underestimate, the work might not be worth their time.

Because the worker is so careful, it can take a long time for them to produce the estimate. But that’s frustrating — when you ask for an estimate, you really are asking for the magnitude of the cost. Will this be $10 or $100 or $1 000? That’s all you really want to know on a first visit.

Please help the worker make the type of estimate you desire. Write a program that, given the worker’s estimate, reports just the magnitude of the cost — the number of digits needed to represent the estimate.

[입력]

Input begins with a line containing an integer N (1 ≤ N ≤ 100). The next N lines each contain one estimated cost, which is an integer between 0 and 10100. (Some of the workmen overcharge quite a bit.)

[출력]

For each estimated cost, output the number of digits required to represent it.

	int *arr = new int[test];

	for(int i = 0; i < test; i++){
		string input;
		cin >> input;

		arr[i] = input.length();
	}

	for(int i = 0; i < test; i++)
		cout << arr[i] << "\n";
}
