Give an example of an occasion when you used logic to solve a problem

Write a program whose input is two integers and whose output is the two integers swapped.

Tpy6a [65]

Answer:

The program to this question can be given as:

Program:

#include <iostream> //header file

using namespace std; //using namespace.

void SwapValues(int* userVal1, int* userVal2); //function declaration.

void SwapValues(int* userVal1, int* userVal2) //function definition.

{ //function body.

//perform swapping

int t = *userVal1;

*userVal1 = *userVal2;

*userVal2 = t;

}

int main() //main method

{

int n1, n2; //define variable

cout<<"Enter first number :"; //message

cin>>n1; //input by user.

cout<<"Enter second number :"; //message

cin>>n2; //input by user.

SwapValues(&n1,&n2); //calling function.

cout<<"Swapped values"<<endl;

cout<<"first number is :"<<n1<<endl; //print value

cout<<"second number is:"<<n2<<endl; //print value

return 0;

}

Output:

Enter first number :3

Enter second number :8

Swapped values

first number is :8

second number is :3

Explanation:

The description of the above C++ language program can be given as:

In the program, firstly we include the header file. Then we declare and define a function that is "SwapValues()" function in the function we pass two integer variable that is "userVal1 and userVal2" inside a function, we define an integer variable that is "t" and perform swapping.
Then we define the main function in the main function we define two variables that is "n1 and n2" this variable is used to take value-form user. then we pass this value to function and print the function values.

State 3 file formats explain them in an understanding manner apart from Microsoft word and PDF

natita [175]

Answer:

Hope below explanations are enough.

Explanation:

1. JPEG (or JPG) - Joint Photographic Experts Group

JPEGs might be the most common file type you run across on the web, and more than likely the kind of image that is in your company's MS Word version of its letterhead. JPEGs are known for their "lossy" compression, meaning that the quality of the image decreases as the file size decreases.

You can use JPEGs for projects on the web, in Microsoft Office documents, or for projects that require printing at a high resolution. Paying attention to the resolution and file size with JPEGs is essential in order to produce a nice looking project.

2. PNG - Portable Network Graphics

PNGs are amazing for interactive documents such as web pages, but are not suitable for print. While PNGs are "lossless," meaning you can edit them and not lose quality, they are still low resolution.

The reason PNGs are used in most web projects is that you can save your image with more colors on a transparent background. This makes for a much sharper, web-quality image.

3. GIF - Graphics Interchange Format

GIFs are most common in their animated form, which are all the rage on Tumblr pages and in banner ads. It seems like every other day we have a new Grumpy Cat or Honey Boo Boo animated GIF. In their more basic form, GIFs are formed from up to 256 colors in the RGB colorspace. Due to the limited number of colors, the file size is drastically reduced.

This is a common file type for web projects where an image needs to load very quickly, as opposed to one that needs to retain a higher level of quality.

4. TIFF - Tagged Image File

A TIF is a large raster file that doesn't lose quality. This file type is known for using "lossless compression," meaning the original image data is maintained regardless of how often you might copy, re-save, or compress the original file.

Despite TIFF images' ability to recover their quality after manipulation, you should avoid using this file type on the web -- it can take forever to load. TIFF files are also commonly used when saving photographs for print.

5. PSD - Photoshop Document

PSDs are files that are created and saved in Adobe Photoshop, the most popular graphics editing software ever. This type of file contains "layers" that make modifying the image much easier to handle. This is also the program that generates the raster file types mentioned above.

The largest disadvantage to PSDs is that Photoshop works with raster images as opposed to vector images.

What are the primary benefits of relying on systems development standards?

Sunny_sXe [5.5K]

Answer:

The benefits of relying on System Development Standards is explained below.

Explanation:

There are many benefits of having a Well Defined Systems Development. It helps in having a pre - planned and well defined structure before the project starts. It helps in having a Clear view of the whole project and also each phase of the whole System Development. It helps in having an understanding of cost required and the revenues generated at each phase of the whole system development. It helps in having an understanding of the goal of each phase and procedures need to be followed for that particular goal. It also helps in having the quality checked and the improvements need to be made for the desired quality.

State the base of correct addition of 27 + 6 =34

Andrej [43]

Answer:

9

Explanation:

lets do calculations with ONLY the rightmost digits, ie., 7 + 6 = 4, so we're ignoring the carry.

Then, following must be true as well:

7+5 = 3

7+4 = 2

7+3 = 1

7+2 = 0 <= this reveals our base 9

7+1 = 8

7+0 = 7
