there is this code in php named

<?php
$arr1[6]={1,2,3,4,5,6};
$arrcount=count(arr1);
echo $arrcount;//6 is the answer
?>

No. Arrays in C/++ don't have sizes in the sense that it cannot be obtained at run time. There's a way to obtain the size of an array at compile time, but it doesn't apply to all arrays. It depends on how the array was created: sizeof(array)/sizeof(*array)

C++ (not C), however, defines in its standard library a container called "vector", whose size can be obtained at run time.
