2. (40 points) You need to understand array, pointer and pointer arithmetic to complete this exercise. And you should be able to figure out the answers without actually compiling and running the program.

#include

int main(int argc, char *argv[])

{

char a, *pc, c[8];

int i, *pk, k[8];

a='N';

pc=&(c[7]);

pk=&(k[0]);

for (i=0; i<8; i++)

{

*pc=a-(char)i;

pc--;

*pk=i+5;

pk++;

}

return 0;

}//end of main

Write out the memory map for the above C code in the following table. For array variables, list the address range for the entire array. Assume the memory address starts from 100, that is, the address for a is 100. Suppose sizeof(char)=1, sizeof(int)=4 and the size of a memory address (a pointer) is 8 bytes. You may assume there is no gap in memory between the variables. (18 points)

Variable	Start address	End address
a
pc
c
i
pk
k

Additionally, show values of the variables in the following table at the end of execution of the for loop before the main function returns. (For the two array variables c and k, list the contents of all array elements.) (18 points)

Variable	Value
a
pc	Use an expression involving c to represent pcs value
c
i
pk	Use an expression involving k to represent pks value
k

How many bytes in total does the code allocate for the variables? (4 points)
