Taking a suitable example in c language explain the of call by value and call by reference concepts.

Degger [83]

Answer: The difference between call by value and call by reference is that in call by value the actual parameters are passed into the function as arguments whereas in call by reference the address of the variables are sent as parameters.

Explanation:

Some examples are:

call by value

#include <stdio.h>

void swap(int, int);

int main()

{ int a = 10, b= 20;

swap(a, b);

printf("a: %d, b: %d\n", a, b);

}

void swap(int c, int d)

{

int t;

t = c; c = d; d = t;

}

OUTPUT

a: 10, b: 20

The value of a and b remain unchanged as the values are local

//call by reference

#include <stdio.h>

void swap(int*, int*);

int main()

{

int a = 10, b = 20;

swap(&a, &b); //passing the address

printf("a: %d, b: %d\n", a, b);

}

void swap(int *c, int *d)

{

int t;

t = *c; *c = *d; *d = t;

}

OUTPUT

a: 20, b: 10

due to dereferencing by the pointer the value can be changed which is call by reference

Determine the number of bytes necessary to store an uncompressed RGB color image of size 640 × 480 pixels using 8, 10, 12 and 14

dexar [7]

Answer:

For 8 bits / Color Channel: 921, 600 bytes.

For 10 bits / Color Channel: 1,152,000 bytes.

For 12 bits / Color Channel: 1,382,400 bytes.

For 14 bits / Color Channel : 1,612, 800 bytes.

Explanation:

Un uncompressed RGB color image of 640 pixels wide by 480 pixels height (VGA resolution) uses 3 samples of x bits fin order to represent the quantity of each primary color (red, green and blue) in a given pixel of the image.

So, if we use 8 bits/ sample, we can calculate the bytes needed to store a complete image as follows:

640*480*3*8 bits = 7, 372,800 bits. (1)

As, by definition, 1 byte= 8 bits, we have:

Nº of bytes = 7,372,800 / 8 = 921,600 bytes. (2)

In order to get the bytes needed to store the same image, using 10, 12 and 14 bits/ sample, all we need is replacing 8 by 10, 12 and 14 in (1), and then dividing by 8 as in (2).

Proceeding in this way we obtain:

640*480*3*10 = 9,216,000 bits ⇒ 1,152,000 bytes.

640*480*3*12 = 11,059,200 bits ⇒ 1,382,400 bytes.

640*480*3*14= 12,902,400 bits ⇒ 1,612,800 bytes.

Which of the following best describes how computing devices represent information

olganol [36]

Answer:

A system is which a computer is used to turn data into information best describes a computer-based information system.

A text code is a system that uses binary numbers (1s and 0s) to represent characters understood by humans (letters and numerals). y An early text codesystem, called EBCDIC, uses eight-bit codes, but is used primarily in older mainframe systems.

Data processing is simply the conversion of raw data to meaningful information through a process. ... Similar to a production process, it follows a cycle where inputs (raw data) are fed to a process (computer systems, software, etc.) to produce output (information and insights).

The central processing unit consists of electronic circuits that interpret and execute program instructions, as well as communicate with the input, output, and storage devices. It is the central processing unit that actually transforms data into information. Data is the raw material to be processed by a computer.
