Part A
Write a program to evaluate the first 20 numbers of Fibonacci series. Use the stack (memory) to store the calculated series. Your debugger output should look like the following screenshot.
Part B
Modify the program matrixmul.s to add two matrices and store it in a third matrix. Your output could show all three matrices in memory.
Note : Make sure you DO NOT Copy & Paste the above snapshot. You have to make the snapshot of your own program. Please send this with assembly code and a snapshot of debugger session with all important output.
Part -C
Modify the subroutine to add two complex numbers (Slide -1) to multiply two complex numbers. Your debugger output should be in the format shown in Slide -2.The product of two complex numbers a + ib and c + id is given by (ac - bd) + i(bc + ad)
Slide -1
/**
struct complex complex_add(struct complex* c1, struct complex* c2) {
struct complex c;
c.re = c1->re + c2->re;
c.im = c1->im + c2->im;
return c;
}
