This is my c++ homework, and I get a question about the following code written by the professor. I did not understand the "p++" in the code, and I do not understand why we have to write this.

Please Help Language C++ Write a C++ Program to Multiply Two Matrix Using Multi-Dimensional Arrays. This program takes two matrices of order r1*c1 and r2*c2 respectively. Then, the program multiplies these two matrices (if possible) and displays it on the screen. Note: the use of pointers is not allowed and everything needs to be done in the main() function.

write in c++ Write ONE program that contains the following (#includes are NOT necessary). [Hint: be very careful with your pointer syntax] Write a function copies with two int parameters, named n and x. It should dynamically allocate a new array of size n. The function should then copy the value in x to every position in the array. The function should return a pointer to the new array. In the main function, call the copies function from part 1. with size 5 and value -1. Output the resulting array to the screen, and deallocate the array. In your main function, add code to declare and initialize two integer variables y and z to 10 and 3. Then call the function increment which has the prototype below. The call should result in incrementing the value in y by z (so y will become 13). void increment (int *a, int b); //do NOT define this function// this function adds b to the value pointed to by the first argument
