Answer:
The correct answer to the following question will be Error-detection.
Explanation:
Error-detection: The detection of errors caused during the transmission from the transmitter to the receiver by damage and other noises, known as Error-detection. This error-detection has the ability to resolute if something went wrong and if any error occurs in the program.
There are mainly three types of error-detection, these types can be followed:
- Automatic Repeat Request (ARQ)
- Forward Error Correction
- Hybrid Schemes
There are two methods for error-detection, such as:
- Single parity check
- Two-dimensional parity check
Answer:
The correct answer to this question is given below in the explanation section.
Explanation:
This question is about integrated development environments (IDEs) that support multiple high-level programming languages.
All mentioned IDEs such as Eclipse, Visual Studio, and Xcode support multiple high-level programming languages except Linux.
Using Eclipse, you can do Java programming easily and can build Java-based programs, and also you can do android programming in Eclipse while importing required android settings and libraries. Visual Studio is a Microsoft IDE, in which you can build desktop, web, and mobile, and windows phone app easily using high-level programming. Xcode is an integrated development environment for macOS containing a suite of software development tools developed by Apple for developing software for macOS, iPadOS, iOS, watchOS, and tvOS.
While Linux is not an IDEs, it is an open-source operating system based on Linux kernel.
Answer:
enables you to make changes to one part of an image without accidentally changing other parts
Explanation:
Computer aided designs incorporate the use of multiple layers in drawings. The first layer is known as the layer 0, while the present layer the designer is working on is known as the current layer. The advantage of the incorporation of layers in designs include the following
1. It helps objects to be altered, grouped, hidden and moved as the designer wishes.
2. Layers can be grouped and worked on separated and common properties like color and line weight assigned to them.
3. Layers can be manipulated as the user wishes. They can be locked, frozen, turned off, etc. Locking prevents accidental changes being made on objects.
Answer:
/*C++ program that prompts user to enter the name of input file(input.txt in this example) and print the sum of the values in the file to console. If file dosnot exist, then close the program */
//header files
#include <fstream>
#include<string>
#include <iostream>
#include <cstdlib> //needed for exit function
using namespace std;
//function prototype
int fileSum(string filename);
int main()
{
string filename;
cout << "Enter the name of the input file: ";
cin >> filename;
cout << "Sum: " << fileSum(filename) << endl;
system("pause");
return 0;
}
/*The function fileSum that takes the string filename and
count the sum of the values and returns the sum of the values*/
int fileSum(string filename)
{
//Create a ifstream object
ifstream fin;
//Open a file
fin.open(filename);
//Initialize sum to zero
int sum=0;
//Check if file exist
if(!fin)
{
cout<<"File does not exist ."<<endl;
system("pause");
exit(1);
}
else
{
int value;
//read file until end of file exist
while(fin>>value)
{
sum+=value;
}
}
return sum;
}//end of the fileSum
Explanation:
This is a C++ program that prompts user to enter the name of input file(input.txt in this example) and print the sum of the values in the file to console. If file dosnot exist, then close the program.
