Re: INT ARRAY IN C

sizeoff (int_array);

But if you pass this vector to a fuction by refrence you must pass its length to function, because "sizeoff (int_array);" will not work correctly at this function.

The word "length" is unclear.
sizeof(hello) is the number of bytes.
sizeof(hello)/sizeof(*hello) is the number of elements.

Algo


get the sizeof Array sizeof(Array), It will give you sizeof(data type)*number of elements in Array

then get size of data type sizeof(*data type)

last sizeof(Array)/sizeof(*data type) this will give you total number of elements in Array

got it gr8

Hi,
the simplest way i think is
num of elements = sizeof(hello)/ sizeof(int)

yes it's the easy way

sizeof(array)/sizeof(int);
