Answer and Explanation:
In C programming language:
char fun(int*a, int*b){
printf("enter two integers: ");
scanf("%d%d",a,b);
int e;
printf("please enter a character: ");
e=getchar();
return e;
}
int main(int argc, char *argv[]) {
int d;
int f;
int g;
fun();
printf("%d%d%d", d, f, g);
}
We have declared a function fun type char above and called it in main. Note how he use the getchar function in c which reads the next available character(after the user inputs with printf()) and returns it as an integer. We then return the variable e holding the integer value as char fun() return value.

a do-while loop that continues to prompt a user to enter a number less than 100, until the entered number is actually less than 100. End each prompt with newline Ex: For the user input 123, 395, 25, the expected output is:Enter a number (<100):Enter a number (<100):Enter a number (<100):Your number < 100 is: 25
Answer:
Explanation:
import java.util.Scanner;
//Declare the class NumberPrompt.
public class NumberPrompt
{
public static void main(String args[])
{
/*Declare the variable of scanner class and allocate the
memory.*/
Scanner scnr = new Scanner(System.in);
//Initialize the variable userInput.
int userInput = 0;
/* Your solution goes here*/
//Start the do-while loop
do

//Prompt the user to enter the number.
System.out.println("Enter a number(<100)");
/*Store the number entered by the user in the
variable userInput.*/
userInput=scnr.nextInt();

Consider a DataFrame named df with columns named P2010, P2011, P2012, P2013, 2014 and P2015 containing float values. We want to use the apply method to get a new DataFrame named result_df with a new column AVG. The AVG column should average the float values across P2010 to P2015. The apply method should also remove the 6 original columns (P2010 to P2015). For that, what should be the value of x and y in the given code?
Answer:
x = 1
y = 1
Explanation:
The apply method has the axis argument which enables it to use the applied function either across the rows or columns, by passing the value 1 to the axis argument, the mean of at each index is calculated, (across the column) such that the length of the AVG column is equal to the lengtb of the original dataframe.
The drop method is used in pandas to remove row or column entry from a dataframe. To remove columns from a data table, the value 1 is passed to the axis argument of the drop method. Hence, passing 1 to the axis argument removes all 6 columns leaving only the AVG column in result_df.
The internet's data pathways rely on what kind of hardware device to route data to its destination?

Answer:
Routers
Explanation:
Essentially a router is a device used in networking that route packets of data from one computer network to another.
Answer:

How to prepare and draw a corresponding flowchart to compute the sum and product of all prime numbers between 1 and 50
Answer:
Create boxes with the following content
Initialize sum to 0, product to 1 and number to 1Check if number is a prime. If yes, update sum += number and product *= numberIncrease number by 1If number is <= 50, go back to "check" block.The check block has a diamond shape.
At the "yes" branch of the check block, you can create separate blocks for updating the sum and the product.
Connect the blocks using arrows.
Indicate the start and the end of the flow using the appropriate symbols.

Which of the following expressions would you use to test if a char variable named choice is equal to "y" or "Y"? a. choice.tolower = "y" || "Y" b. choice.tolower = "y" c. tolower(choice) = "y" d. tolower(choice) = "y" || "Y"
Answer:
choice.tolower == "y"
Explanation:
The tolower method is a string method in c# that converts all characters in a string to lowercase characters(if they are not already lowercase letters) except special symbols which remain the same example "#" symbol.
The tolower method does not take any arguments, therefore to use it, we simply chain it to our string variable(dot notation) and use a comparison operator "==" that evaluates to true or false based on whether the values returned on both sides are equal.
