Question

You are to write a MIPS program that will execute the following simple C statement, f = 2*g + 5*h; You can implement the multiplication in any way you choose. You should assume that f, g, and h are of type int and therefore are 4 bytes in length. You must declare the variables appropriately and initialize them to some value of your choice. The values of g and h should be clearly displayed on the screen and the output of the instruction should be displayed on the screen as well. All output should be clearly labeled.
