## Check if all elements in array are in string in C++

This tutorial will discuss about a unique way to check if all elements in array are in string in C++. To check if all the strings from an array are present in another string, we will use the std::all_of() function from STL Algorithms. The std::all_of() function accepts three arguments, The std::all_of() function will apply the …

## Check if all elements in array are false in C++

This tutorial will discuss about a unique way to check if all elements in array are false in C++. To check if all the elements in array are false, we will use the std::none_of() function from STL. It accepts the start, and end of a range, and a callback function (predicate) as arguments. Then it …

## Check if All elements in Array are in another array in C++

This tutorial will discuss about unique ways to check if all elements in array are in another array in C++. Table Of Contents Technique 1: using std::all_of() Technique 2: using std::includes() Summary Technique 1: using std::all_of() Suppose we have two arrays, and now we want to check if all elements of one array are present …

## Check if All elements of Array are equal in C++

This tutorial will discuss about a unique way to check if all elements in array are equal in C++. To check if all elements of an array or equal, we will use the STL algorithm std::adjacent_find(). The std::adjacent_find() function accepts 3 arguments, For every ith element in the array, the std::adjacent_find() function will call the …

## Check if All elements in Array are null in PHP

This tutorial will discuss about a unique way to check if all elements in array are null. We can use the array_reduce() function to get the work done here. The array_reduce() function accepts three arguments, It then applies the given callback function on all the elements of array, and reduce them to a single value. …
