2) Please create a C program for the following: (25 points) a. Suppose the US dollar to Korean Won is 0.85 dollars to 1000 won.
Zanzabum

Answer:

In C:

#include <stdio.h>

int main(){

       float won,usd,rupee,dinar,peso;

       printf("Won: ");

       scanf("%f", &won);

       usd = won * 0.85/1000;

       rupee = won * 0.85 * 0.14/1000;

       dinar = won * 0.85 * 0.048/1000;

       peso = won * 0.85 * 1.41/1000;

       printf("USD = %f\n", usd);

       printf("Rupee = %f\n", rupee);

       printf("Dinar = %f\n", dinar);

       printf("Peso = %f\n", peso);

   return 0;

}

Explanation:

This declares all variables as float

float won,usd,rupee,dinar,peso;

This prompts the user for Korean Won

       printf("Won: ");

This gets the input for won

       scanf("%f", &won);

This converts to usd

       usd = won * 0.85/1000;

This converts to rupee

       rupee = won * 0.85 * 0.14/1000;

This converts to dinar

       dinar = won * 0.85 * 0.048/1000;

This converts to peso

       peso = won * 0.85 * 1.41/1000;

The next four lines print the converted currencies

       printf("USD = %f\n", usd);

       printf("Rupee = %f\n", rupee);

       printf("Dinar = %f\n", dinar);

       printf("Peso = %f\n", peso);

Answer:

;Macro mReadInt definition, which take two parameters

;one is the variable to save the number and other is the length

;of the number to read (2 for 16 bit and 4 for 32 bit) .

Explanation:

For an assembly code/language that has the conditions given in the question, the program that tests the macro, passing it operands of various sizes is given below;

;Macro mReadInt definition, which take two parameters

;one is the variable to save the number and other is the length

;of the number to read (2 for 16 bit and 4 for 32 bit) .

%macro mReadInt 2

mov eax,%2

je read2

cmp eax, "2"

je read1

read1:

mReadInt16 %1

cmp eax, "2"

je exitm

read2:

mReadInt32 %1

exitm:

xor eax, eax

Name and describe the various features of the PC support pages of About.com.
erma4kov [3.2K]

Answer: Awnser below.

Explanation:

Basically, what you're going to need for a computer from my basic knowledge is a motherboard, of course, this is so you can actually use your computer. You'll need a PSU, or so called, a power supply. This will give power to your motherboard and the other components with it. You will need a CPU, this is basically the brains of the computer. This will run your operating system, and main componets. A GPU, this will give you a display for your monitor. And of course, ram. Ram will be giving you display for your monitor, and for running tasks.

For more components, you would need a hard drive, or an SSD, which will store your files and operating system. And of course, a keyboard, mouse, and monitor.
