In this program, we are going to share a C++ program to find Majority element in an array. If you are a beginner and want to start learning the C++ programming, then keep your close attention in this tutorial as I am going to share a c++ program to find Majority element in an array.
Copy the below C++ program and execute it with the help of GCC compiler. At the end of this program, We have shared the output of this program.
