Can someone explane why sizeof(n[2])=4?

Question

//Note:assume int is 4 bytes
int main() { //sizeof(n)=200
int n[50]; //sizeof(n[2])=4
cout<<sizeof(n)/sizeof(n[2]);
} //Output: 50

Answer 1

If you're asking why `sizeof(n[2])` yields 4 then it is because <n> is an array of int, so each element in array <n> itself is an int, which is (commonly) 4 bytes in memory allocation size.

If I misunderstood your question then explain your intention more clearly : )

Answer 2

n[2] is only one integer, so n[2] = 4 bytes
