user declaring the size of array?

[jakvrh1]

is it possible to use this code ?

#include <iostream>

int main(int argc, const char * argv[]) {
	int number = 0;
	std::cout << "napis cifro za array\n";
	std::cin >> number;

	int array[number];

	
	std::cout << "array doug " << sizeof(array) / sizeof(int) << "\n";

	return 0;
}

It does work on xcode but doesn't in microsoft visual studio 2013. Where is the problem?

The size of the array has to be a compile time constant.

you need to dynamically allocate it. And why does function main have parameters?

It's one of two forms of main that is guaranteed to work on every C++ compiler. It allows you to read command line arguments that was passed to the program.
