The preprocessor (cpp) modifies the original C program according to
directives that begin with the # character. For example,
the #include <stdio.h>.

The main memory is a temporary storage device that holds both a program and the
data in it such that it consists of a collection of static random access memory (SRAM)
chips.

address to select which word should be read or
written. Examples of random-access memories include :
a. | the virtual memory system of
a
processor | c. | a and b | b. | the register file, where register identifiers
serve as the addresses | d. | None

Compile the following C program called a.c and provide the assembly code
file a.s
#include <stdio.h>
int main()
{ int i, j=7,
sum=0;
for(i = 1; i < 25;
i++)
sum+=
i+j*3;
printf("Sum=%d\n", sum);
return 0;

Fill in the table
below showing the effects of the different shift operations on singlebyte quantities. The best way to
think about shift operations is to work with binary representations. Convert the initial values to
binary, perform the shifts, and then convert back to hexadecimal. Each of the answers should be 8
binary digits or 2 hexadecimal digits.
