bytes!!!

Hello!!!I have a question... How many bytes has the array int b[5]={0,0,0,0,0}???

My teacher said it has 18 bytes,but I think it has 10 bytes...
Which answer is the right one???

b is an array of 5 ints. So the answer must be a multiple of 5 - so the teacher's answer is wrong!

The correct answer depends upon the size of an int. If an int size is 16 bits (ie 2 bytes) then the correct answer is 10. If an int size is 32 bits (ie 4 bytes) then the correct answer is 20.

Try this program

Code:

---

#include <iostream>
using namespace std;

int main()
{
int b[5]={0,0,0,0,0};

        cout << "An int has " << sizeof(int) << " bytes" << endl;
        cout << "int b[5] has " << sizeof(b) << " bytes" << endl;
        return 0;
}

---

On my system it prints 4 and 20.

Great... Thank you!!! :)
