WebIf your array has been defined as having 8 elements, for the compiler it has 8 elements, no matter whether you initialized only 5 of them. You cannot determine the size of an array … WebPrint unique elements of the array in the same order as they appear in the input. Note: Do not use any inbuilt functions/libraries for your main logic. Input Format: First line of input contains a single integer N - the size of array and second line contains array elements. Constraints: 1 <= N <= 100 0 <= ar [i] <= 109 Output Format: stier law firm

If I have an array of 30 strings, my system sets aside 24 bytes for each element(string) of the array. See more In C++20, there is a new better way added to the standard library for finding the length of array i.e. std:ssize(). This function returns a signed value. See more In C++17 there was a better way (at that time) for the same which is std::size() defined in iterator. P.S. This method works for vectoras well.
