Loop is a control structure that causes a statement or group of statements to repeat.Before entering a loop, the first input, or the accumulator where the total will be kept is retrieved to an initial value, usually zero.

Given an int variable n that has been initialized to a positive value and, in addition, int variables k and total that have alre

Fudgin [204]

Answer:

The c++ program to implement the while loop is given below.

#include <iostream>

using namespace std;

int main() {

// declaration of integer variables

int k, n, total;

// initialization of integer variables

k=1, n=4, total=0;

// loop executed till value of k becomes equal to value of n

while( k <= n ){

// cube of every integer is added to the variable total

total = total + ( k * k * k );

// value of k is incremented to go to the next number

k = k + 1 ;

}

return 0;

}

Explanation:

The program begins with the declaration of integer variables.

int k, n, total;

This is followed by initialization of these variables.

k=1, n=4, total=0;

The while loop runs over the variable k which is initialized to 1. The loop runs till value of k reaches the value of integer n.

First, cube of k is computed and added to the variable total.

After first execution of the loop, total is initialized to the cube of 1.

Next, value of variable k is incremented by 1 so that k is initialized to next integer.

After first execution of the loop, k is incremented from 1 to 2.

while( k <= n )

{

total = total + ( k * k * k );

k = k + 1 ;

}

When the value of k reaches the value of integer n, the cube of n is calculated and added to the variable, total.

When k is incremented, it becomes more than n and hence, loop gets terminated.

As the return type of main is int, the program terminates with the statement shown below.

return 0;

No output is displayed as it is not mentioned in the question.

No user input is taken as it is mentioned that integer variables are already initialized.

Write a function named dice_eval that accepts two parameters representing numeric dice values and returns a string describing th

Zigmanuir [339]

Following are the "dice_eval" method code into python language.

Program Explanation:

Defining a method "dice_eval" that takes two variables "d1,d2" in its parametes.
Inside the method, multiple conditional statements were used that adds the parameter values and calculates its value which can be defined as follows:
In the if block, it adds the parameters and uses or gate that check its value that is equal to 7 or 11. so, it will return a string message that is 'Winner!'.
In the elif block, it adds the parameters and uses or gate that check its value that is equal to 2 or 3 or 12. so, it will return a string message that is ' C r aps ! '.
In the else block, it uses a return keyword that adds parameter value and prints a string value.
Outside the method "d1,d2" is declared that inputs the value from the user-end, and passes the value into the method, and prints its value.

Program:

def dice_eval(d1, d2):#defining a method dice_eval that takes two parameters

if (d1+d2)==7 or (d1+d2)==11:#defining if block that adds parameter value and use or operator to check its value

return 'Winner!'#return string value

elif (d1+d2)==2 or (d1+d2)==3 or (d1+d2)==12:#defining elif block that adds parameter value and use or operator to check its value

return 'C r aps!'#return string value

else:#defining else block

return 'Point is '+str(d1+d2)#return string value with adding parameter

d1=int(input())#defining d1 that input value

d2=int(input())#defining d2 that input value

print(dice_eval(d1,d2))#calling method and print its return value
