Couldn't understand working of Sizeof in array

#1

int a[ ]={1,2,3,4}
int n= sizeof(a) / sizeof(int)

here i cannot understand the logic of how sizeof() works
and what the sizeof() calculates?

#2

Hello @aggarwal.naman21,

sizeof determines the size, in bytes, of a variable or data type,
sizeof(a) = 4*4 = 16
sizeof(int) = 4

n = 16/4 = 4
