Hi, can you help me write a C++ code?

Create an array with a capacity of 20 elements. Fill the array with 10 random numbers. You can do this however you want. In this array try to the following or any variations of the following:

1. Remove all even values in the array

2. Remove the first and last values in the array

3. Insert a new random number after every existing element in the array and make sure you are not going over the capacity.
