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:
Option B is the correct answer.
Explanation:
- In the above code, the loop will execute only one time because the loop condition is false and it is the Do-While loop and the property of the Do-while loop is to execute on a single time if the loop condition is false.
- Then the statement "x*=20;" will execute one and gives the result 200 for x variable because this statement means "x=x*20".
- SO the 200 is the answer for the X variable which is described above and it is stated from option B. Hence it is the correct option while the other is not because--
- Option A states that the value is 10 but the value is 200.
- Option C states that this is an infinite loop but the loop is executed one time.
- Option D states that the loop will not be executed but the loop is executed one time
Answer:
def analyze_text(sentence):
count = 0
e_count = 0
for s in sentence:
s = s.lower()
if s.isalpha():
count += 1
if s == "e":
e_count += 1
return "The text contains " + str(count) + " alphabetic characters, of which " + str(e_count) + " (" + str(e_count*100/count) + "%) are ‘e’."
Explanation:
Create a function called analyze_text takes a string, sentence
Initialize the count and e_count variables as 0
Create a for loop that iterates through the sentence
Inside the loop, convert all letters to lowercase using lower() function. Check each character. If a character is a letter, increment the count by 1. If a character is "e", increment the e_count by 1.
Return the count and e_count in required format
Answer:
public class Calculator {
private int total;
private int value;
public Calculator(int startingValue){
// no need to create a new total variable here, we need to set to the our instance total variable
total = startingValue;
value = 0;
}
public int add(int value){
//same here, no need to create a new total variable. We need to add the value to the instance total variable
total = total + value;
return total;
}
/**
* Adds the instance variable value to the total
*/
public int add(){
// no need to create a new total variable. We need to add the value to the instance total variable
total += value;
return total;
}
public int multiple(int value){
// no need to create a new total variable. We need to multiply the instance total variable by value.
total *= value;
return total;
}
//We need to specify which value refers to which variable. Otherwise, there will be confusion. Since you declare the parameter as value, you need to put this keyword before the instance variable so that it will be distinguishable by the compiler.
public void setValue(int value){
this.value = value;
}
public int getValue(){
return value;
}
}
