"To preform specific useful computing tasks, like word processing and calculation" is the correct answer. This is the whole purpose of system software. The third answer is some other type of software(third party software?) and the fourth answer is most likely a compiler. Those are the easiest to take off. The second could also work.
The two answers I would go with are the first and the second.
Answer: C. File encryption
Explanation: To ensure security and privacy of files and its content, encrypting the file may be an option. File encryption refers to a process of ensuring the security and privacy of individual files so as to prevent unauthorized access to the content. File encryption works by setting up a security key which will be requested or needed when the file is being clicked such that only users or individuals with the authorized pass code or password can open and read its content or modify the file, this is called file decryption.
Answer:
int age = 10;
switch (age){
case 0:

break;
case 2:
System.out.println("toddler");
break;
case 3:
case 4:
case 5:
System.out.println("early childhood");
break;
case 6:
case 7:
System.out.println("young reader");
break;
case 8:
case 9:
case 10:
System.out.println("elementary");
break;
case 11:
case 12:
System.out.println("middle");
break;
case 13:
System.out.println("impossible");
break;
case 14:
case 15:
case 16:
System.out.println("high school");
break;
case 17:
case 18:
System.out.println("scholar");

default:
System.out.println("ineligible");
}
Explanation:
In java and many other programming languages, a switch statement is a way of having multiple branching options in a program. This is usually considered a more efficient way than using multiple if....else if statements. and the expression variables could be byte, char int primitive data types. etc. every branch (option) in a switch statement is followed by the break statement to prevent the code from "falling through". In the question The variable age is declared as an int and initialized to 10. and tested against the conditions given in the question.
Tape a spoiler to the trunk.
Answer:
Expression for the above problem in python language:
userNum=int(input("Enter the value of user_Num")) #it is used to take input.
if(userNum>(-10)): #if statement
print("The value of the userNum is greator")
elif(userNum==(-10)): #elif statement
print("The value of the userNum is equal to -10")
else: #else statement.
print("The value of the userNum is small")
Output:
- If the user input is (-10), it will print equal.
- If the user input 10, it will print greator message.
Explanation:
- The above program or expression is in python language, where the first line is used to render a message to the user take the input and store it into a userNUM variable.
- Then the second line is used to check the user num value to be greater with the help of if statement.
- Then the third statement is used to check the user num value to be equal with the help of elif statement.
- Then the else statement will execute when the if and the elif statement will not true.
