Write a C program to add, subtract, multiply, find the complex conjugate, magnitude, and divide 2 complex numbers. Read the 2 complex numbers from a file, and write the solutions to the same file using append as the file option. Use a structure to define the complex number. Note: a complex number is in the form of a + bi where i = square root of -1. Note: (a+bi) + (c+di) = (a+c) + (b+d)i Similarly for subtraction. For multiplication, note that i*i = -1. For division, you will need to find the complex conjugate of the complex number. If z = a + bi, the complex conjugate z* = a bi. Division becomes: (a+bi)/(c+di) = (ac+bd)/(c2+d2) + i(bc-ad)/(c2+d2) Please write this in C programming "not" c++ etc.
