sizeof(array)/sizeof(array[0]) _countof(array) These tell you thesize (capacity)of the array, i.e. how muchstorage spacethere is in the array. They donottell you anything about the currentcontentof the array! Specifically, they donottell you the "length" of the string, i.e. how ...

Usesizeof()Function to Calculate Array Length in C++ In C++, thesizeof()functionallows us to determine the size of an array at compile time. Syntax: sizeof(datatype) Thesizeof()function takes a data type (e.g.,int,double,char, etc.) as its parameter and returns the size of that ...

Given an array of integers where 1 ≤ a[i] ≤n(n= size of array), some elements appear twice and others appear once. Find all the elements of [1,n] inclusive that do not appear in this array. Could you do it without extra space and in O(n) runtime? You may assume the returne...
In the main() function, we are creating an object A of class Array, reading integer values by the user of the array using the putArray() function, and finally calling the secondLargest () member function to find out the second largest number in the given integer number in the array. ...

You're trying to access the array at size, not size -1. The "index" will be the index locations where the maximum value is located. Also don't be afraid of a little consistent white space in your calculations: 1234567891011121314151617181920 void findMaxandIndex (int arr[3][5], const ...
