Thread: How can i convert c++ to c (help!!!)

hello everyone, how can i convert this code from C++ to C language. This is quite important to me. Please help me. thanks...

Code:

#include <iostream>
#include <vector>


static const int UPPER_BOUND = 100;


int main() {
	std::vector<int> landings;
	// Push in doubles.
	for (int i = 1; i <= 20; ++i) {
		landings.push_back(2 * i);
	}
	landings.push_back(2 * 25);
	// Push in singles.
	for (int i = 1; i <= 20; ++i) {
		landings.push_back(i);
	}
	landings.push_back(25);
	// Push in trebles.
	for (int i = 1; i <= 20; ++i) {
		landings.push_back(3 * i);
	}


	int nCheckOuts = 0;
	for (int i = 0; i < 21; ++i) {
		int sum = landings[i];
		if (sum < UPPER_BOUND) {
			++nCheckOuts;
		}
		for (int j = 0; j < 62; ++j) {
			sum += landings[j];
			if (sum < UPPER_BOUND) {
				++nCheckOuts;
			}
			for (int k = j; k < 62; ++k) {
				sum += landings[k];
				if (sum < UPPER_BOUND) {
					++nCheckOuts;
				}
				sum -= landings[k];
			}
			sum -= landings[j];
		}
	}
	std::cout << nCheckOuts << std::endl;


	return 0;
}
