Write a C program to display the upper triangular matrix of a 3 times 3 integer matrix. The upper triangular matrix has zeros for all the entries below the main diagonal. For example if A is a 3 times 3 matrix of the form: A = [a d g b e h c f i] Then the upper triangular matrix of A is: [a 0 0 b e 0 c f i] The program should have the following segments: (i) Prompt the user to enter all nine integer elements of the matrix; (ii) Print this matrix out onto the display; (iii)Write a code segment to print the upper triangular matrix of this matrix onto the display. You must implement this with an appropriate looping (repetition) method
