      question on c++ code

      I am writting a program that has three different files and is compiled by a Makefile. The goal is to take a file of text and split it up in different sections and stored in vectors. Then it outputs the information in a standard format. The main is fine and my function declarations are good also I am just having trouble writing the functions. Below are the function names and what they need to do. I have been trying some different ways to write the...

        question on a problem

        I am working on an assignment and it is asking for IPC(instruction s per cycle) and I dont have a formula to figure it out can anyone help. I am given clock rate, instruction number, and time. Its more detailed then what I am asking but w/ a formula I can do the rest.

            how would the bitwise function help.........i wrote a short program

            Code:
            #include<iostream>
using namespace std;

int main()
{

float i = 0.0;
i = 0.1;
cout << &i;

}
            and i get 0xbfe392f4-

            how would i get the bit value?...

              question on mips code

              the following program is trying to copy words from the address in register $a0 to the address in register $a1, counting the number of words copied in register $v0. It will then stop copying when it finds a word equal to 0. i wasnt tring to preserve the contents of register $v1,$a0,$a1. the terminating word should be copied but not counted.

              this is what i have so far can anyone show me the buggs

                how can I convert -2047 into a base 2 complement number? I know how to read the binary but there has to be a way to convert it I just don't know how.

                I also was trying to figure out how to convert MIPS binary representation for the floating-point number 0.1.

                    question on mips and code

                    hey I have a question on understanding a few things. Im trying to understand
                    the following structure of a instruction register.
                    Op code, Address-1, Address-2, are 6 bits, 18 bits, 18 bits respectively

                    What is the maximum number of distinct operation codes that can be recognized and executed by the processor on this machine?

                    would this be 64 which is base 2 to the 6th. or am i doing it wrong

                          Okay I am writting a program that will take input from a file and store it in a string. Then the string is separated at the whitespaces and these separate strings are loaded in a vector. My problem is that how would I index the vector so that the strings I input can be put in a class?

                          okay I have a .h file that looks like this......

struct Date
{
