How did you generate a random number for the user to guess?

From the binary search algorithm, it follows that every iteration of the while loop cuts the size of the search list by half.

Colt1911 [192]

Answer:

True: In binary search algorithm, we follow the below steps sequentially:

Input: A sorted array B[1,2,...n] of n items and one item x to be searched.

Output: The index of x in B if exists in B, 0 otherwise.

low=1
high=n
while( low < high )
{ mid=low + (high-low)/2
if( B[mid]==x)
{
return(mid) //returns mid as the index of x
}
else
{
if( B[mid] < x) //takes only right half of the array
{
low=mid+1
}
else // takes only the left half of the array
{
high=mid-1
}
}
}
return( 0 )

Explanation:

For each iteration the line number 11 or line number 15 will be executed.

Both lines, cut the array size to half of it and takes as the input for next iteration.

Instructions The population of town A is less than the population of town B. However, the population of town A is growing faster

weeeeeb [17]

Answer: The c++ program is given below.

#include <iostream>

using namespace std;

int main() {

float townA, townB, growthA, growthB, populationA, populationB;

int year=0;

cout<<"Enter present population of town A : ";

cin >> townA;

cout<<endl<<"Enter present growth rate of town A : ";

cin >> growthA;

growthA = growthA/100;

cout<<endl<<"Enter present population of town B : ";

cin >> townB;

cout<<endl<<"Enter present growth rate of town B : ";

cin >> growthB;

growthB = growthB/100;

do

{

populationA = townA + (townA * growthA);

populationB = townB + (townB * growthB);

townA = populationA;

townB = populationB;

year++;

}while(populationA < populationB);

cout<<endl<<"After " <<year<< " years, population of town A is "<<populationA << " and population of town B is "<< population<<endl;

return 0;

}

Explanation:

All the variables for population and growth rate are declared with float datatype.

The user inputs the present population of both the towns.

The growth rate entered by the user is the percentage growth.

For example, town A has 10% growth rate as shown in the output image.

The program converts 10% into float as 10/100.

growthA = growthA/100;

growthB = growthB/100;

The above conversion is done to ease the calculations.

The year variable is declared as integer and initialized to 0.

The growth in population is computed in a do-while loop. After each growth is calculated, the year variable is incremented by 1.

The loop continues until population of town A becomes greater than or equal to population of town B as mentioned in the question.

Once the loop discontinues, the final populations of town A and town B and the years needed for this growth is displayed.

The new line is introduced using endl keyword.

The function main has return type int hence, 0 is returned at the end of the program.

Write test programs in java to determine the scope of a variable declared in a for statement. Specifically, the code must determ

xxMikexx [17]

Answer:

public class Main {
public static void main (String [] args) {
for(int i = 1; i < 10; i++){
int num = 0;
num += i;
}
System.out.println(num);
}
}

Explanation:

In programming each variable has its scope. For example, a variable defined within the for loop has no longer exist outside the loop body. To illustrate this we can write a short program as presented above.

Firstly, create a for loop that traverse the number 1 - 10 (Line 5 - 8). Within the loop create a variable num and initialize it with zero (Line 6) and increment it with i value for each iteration (Line 7).

Outside the loop, we try to print the num (Line 9). When we run the program this will result in an error as the num which is declared inside the for loop will no longer exist outside the loop body.
