Write a C program that asks the user how many complex numbers (num_count) they would like to work with, take in that many complex numbers, and output the summation and multiplication of said complex numbers. In doing so, define the following structure: struct Complex { double re; double im; } You should create a variable length array of struct Complex with the num_count inputted by the user. Then, receive user input for each complex number in the a + bi form. You must ensure num_count is of the int data type and that it is greater than 1. You must also ensure that the user enters the complex number in the expected format. Loop through the array of struct Complex and use the addition/multiplication formula shown above to compute the summation and multiplication of all the user-inputted complex numbers. *** Sample output #1: *** Complex number program Please enter number of complex numbers to be used (>1): -5 Invalid input. Please enter number again: 2 Please enter number 1: 1 + ai Invalid input. Please enter number 1 again: -3 + 2i Please enter number 2: 2 + -3i Number 1: -3.0 + 2.0i Number 2: 2.0 + -3.0i Summation of complex numbers: -1.0 + -1.0i Multiplication of complex numbers: 0.0 + 13.0i Sample output #2: *** Complex number program *** Please enter number of complex numbers to be used (>1): 1 + 1i Invalid input. Please enter number again: 3 Please enter number 1: dajfldkafj Invalid input. Please enter number 1 again: 1 + 1i Please enter number 2: -1 + li Please enter number 3: 1 + -1i Number 1: 1.0 + 1.0i Number 2: -1.0 + 1.0i Number 3: 1.0 + -1.0i Summation of complex numbers: 1.0 + 1.0i Multiplication of complex numbers: -2.0 + 2.0i
