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 […]

This tutorial will discuss about a unique way to check if two char arrays are equals. We can use the strcmp() function to compare two char arrays. It accepts two strings (char pointers) as arguments, and compares both the strings alphabetically. If both the strings are equal then it will return 0. So, to check
