Doubt in dynamic memory allocation

#1

The video said if we write
int* a = new int [10000];
cout<<sizeof(a)<<endl;

then the answer should be 4 (as per sir)
but when i tried it answer came out to be 8.
pls explain the difference

#2

i searched that all pointer variables have size 8

#3

is it true?? pointer char, int ,float everyone has a size of 8 bytes??

#4
