Answer:

Incremental ( C )

Explanation:

The incremental backup system should be used since Catherine intends to backup files every morning and this is because Incremental backup  uses the least amount of disk space by simply copying data of files that have been changed after its previous backup session . Instead of copying all the files that it has previously copied in the previous backup session

Trace the evaluation of the following expressions, and give their resulting values. Make sure to give a value of the appropriate
Masja [62]

Answer:

(a)\ 14"."43

(b)\ 0"0"7

(c)\ 2"8 - 2"611

(d)\ 7"(1 + 1)"46

(e)\ "1"23"4"30"7"17

Explanation:

Required

Evaluate each expression

The simple rules to follow are:

(1) All expressions in bracket will be evaluated based on its data type

(2) Divisions will return only integer values

(3) Integers immediately after string values will be concatenated (not added)

So, the results are as follows:

(a)\ 4 + 1 + 9 + "." + (-3 + 10) + 11 / 3

Evaluate till a string is encountered

4 + 1 + 9 = 14

Followed by "."

Then:

(-3 + 10)   = 7

11/ 3 = 3

"." + (-3 + 10) + 11/3 = "."73 -- because expressions after string operations are concatenated.

So, we have:

4 + 1 + 9 + "." + (-3 + 10) + 11 / 3 = 14"."43

(b)\ 8 + 6 * -2 + 4 + "0" + (2 + 5)

Evaluate till a string is encountered

8 + 6 * -2 + 4 =0

"0" + (2 + 5) ="0"7

So, we have:

8 + 6 * -2 + 4 + "0" + (2 + 5) = 0"0"7

(c)\ 1 + 1 + "8 - 2" + (8 - 2) + 1 + 1

Evaluate till a string is encountered

1 + 1 = 2

"8 - 2" + (8 - 2) + 1 + 1 = "8 - 2"611

So, we have:

1 + 1 + "8 - 2" + (8 - 2) + 1 + 1 = 2"8 - 2"611

(d)\ 5 + 2 + "(1 + 1)" + 4 + 2 * 3

Evaluate till a string is encountered

5 + 2 =7

"(1 + 1)" + 4 + 2 * 3 = "(1 + 1)"46 --- multiply 2 and 3, then concatenate

So, we have:

5 + 2 + "(1 + 1)" + 4 + 2 * 3= 7"(1 + 1)"46

(e)\ "1" + 2 + 3 + "4" + 5 * 6 + "7" + (8 + 9)

Since a string starts the expression, the whole expression will be concatenated except the multiplication and the expressions in bracket.

So, we have:

"1" + 2 + 3 + "4" + 5 * 6 + "7" + (8 + 9) = "1"23"4"30"7"17

wolverine [178]

Answer:

Check the explanation

Explanation:

#include<stdio.h>

/*Function to return max sum such that no two elements

are adjacent */

int FindMaxSum(int arr[], int n)

{

 int incl = arr[0];

 int excl = 0;

 int excl_new;

 int i;

 for (i = 1; i < n; i++)

 {

    /* current max excluding i */

    excl_new = (incl > excl)? incl: excl;

    /* current max including i */

    incl = excl + arr[i];

    excl = excl_new;

 }

  /* return max of incl and excl */

  return ((incl > excl)? incl : excl);

}

/* Driver program to test above function */

int main()

{

 int arr[] = {5, 5, 10, 100, 10, 5};

 printf("%d \n", FindMaxSum(arr, 6));

 getchar();

 return 0;
