Answer:

Revisiting "Build a Tower"

Recall in the last section how we made Karel make a tower of tennis balls. We told Karel to move() and turnLeft() and putBall() until we had a tower. At the end of the program, Karel was still at the top of the tower, like as in the picture below.

Stuck at top

Suppose that now we want Karel to come back down from the top of the tower. The first thing we need to do is get Karel facing in the right direction. One way to do this is to tell Karel

turnLeft();

And then tell Karel to

move();

back to the bottom of the tower.

However, telling Karel to turnLeft() three times is not very readable. That's a lot of writing when all we really want is to tell Karel to "turn right."

Explanation:

Hopefully it would help.

write a C program the prints out the size of variables with the following C data types- int, long, unsigned, long long, double,

Anit [1.1K]

C program for finding size of different data types

#include <stdio.h>

//driver function

int main()

{

int a; //declaring a of type int

float b; //declaring b of type float

double c; //declaring c of type double

char d; //declaring d of type char

long e; //declaring e of type long

long long f; //declaring f of type longlong

unsigned g; //declaring g of type unsigned

// Sizeof operator is used to evaluate the size of a variable

printf(" int data type contains: %lu bytes\n",sizeof(a));/*Finding size of int */

printf("float data type contains : %lu bytes\n",sizeof(b));/*Finding size of float */

printf("double data type contains: %lu bytes\n",sizeof(c));/*Finding size of double */

printf("char data type contains: %lu byte\n",sizeof(d));/*Finding size of char */

printf("long data type contains: %lu byte\n",sizeof(e));/*Finding size of long*/ printf("longlong data type contains: %lu byte\n",sizeof(f));/*Finding size of longlong */

printf("unsigned data type contains: %lu byte\n",sizeof(g)); /*Finding size of unsigned */

return 0;

}

Output

int data type contains: 4 bytes

float data type contains : 4 bytes

double data type contains: 8 bytes

char data type contains: 1 byte

long data type contains: 8 byte

longlong data type contains: 8 byte

unsigned data type contains: 4 byte

If the motherboard is not getting power, it will not start the boot. ... A four-year old laptop will not boot and presents error

lakkis [162]

Answer:

The right order of steps you should take to repare the laptop is: D A C B

Explanation:

D. Ask yourself if the laptop is still under warranty: Because they will replace the board for you or give you a new machine.

A. Ask yourself if replacing the motherboard will cost more than purchasing a new laptop: since technology evolve every day, you might consider buying a new faster, better, advanced machine.

C. Find the service manual to show you how to replace the motherboard: the support assistence will guide you trhough the right way of replacing the board.

B. Find a replacement motherboard: choose the specific one or maybe try to find a better model, that can improve your computer performance.

14. Emelia is very concerned about safety and has conducted a study to determine how many bike helmets were replaced at each loc

damaskus [11]

Answer:

Explanation:

Known Variables A = max Daily Rentals

X = Damaged helmets %

lets find the formula to calculate Helmets per location :taking 1st row as an example.

412 = B - (B*13/100)

412 = (100B-13B)/100

412*100 = 87B

B= 412*100/87

Hence, the generic formula becomes : B= A*100/(100-X)

Applying the same formula for each row and then using ROUND function of excel to round off the digits

=ROUND(number,digits) where number is the number you would like to round off and the digits is the number of decimal digits for it to round off. Since we want natural numbers in our example, we will be using digits as 0.

Explanation:

See attached pictures also.

The _________ operator returns the distance in bytes, of a label from the beginning of its enclosing segment, added to the segme

DanielleElmas [232]

Answer:

C. Offset.

Explanation:

An offset operator can be defined as an integer that typically illustrates or represents the distance in bytes, ranging from the beginning of an object to the given point (segment) of the same object within the same data structure or array. Also, the distance in an offset operator is only valid when all the elements present in the object are having the same size, which is mainly measured in bytes.

Hence, the offset operator returns the distance in bytes, of a label from the beginning of its enclosing segment, added to the segment register.

For instance, assuming the object Z is an array of characters or data structure containing the following elements "efghij" the fifth element containing the character "i" is said to have an offset of four (4) from the beginning (start) of Z.
