Question

C programming

Write a function that gets a 2-d array of given dimensions of ints. It returns true if the array contains two rows with exactly the same values in the same order, and returns false otherwise, bool contains_equal_rows(int height, int width, const int ar[height] [width])

Answer 1

Note: Could you plz go through this code and let me know if u need any changes in this.Thank You
