Answer:

Explanation:

The following code is written in Java and is a function/method that takes in an int array as a parameter. The type of array can be changed. The function then creates a counter and loops through each element in the array comparing each one, whenever one element is found to be a duplicate it increases the counter by 1 and moves on to the next element in the array. Finally, it prints out the number of duplicates.

public static int countDuplicate (int[] arr) {

int count = 0;

for(int i = 0; i < arr.length; i++) {

for(int j = i + 1; j < arr.length; j++) {

if(arr[i] == arr[j])

count++;

}

return count;

}

Answer:

The main cause of lack of jobs is due to automation and the ability for computers to do everything faster, more efficiently and effectively.

Explanation:

A specific example - Data entry jobs are redundant from automation programs

Suppose that the tuition for a university is $10,000 this year and increases 4% every year. In one year, the tuition will be $10

Nataliya [291]

Answer:

The programming language is not stated; however, I'll answer using Python programming language (See attachment for proper format)

tuition = 10000

rate = 0.04

for i in range(1,15):

tuition = tuition + tuition * rate

if i <= 10:

print("Year "+str(i)+" tuition:",end=" ")

print(round(tuition,2))

if i == 14:

print("Tuition 4th year after:",end=" ")

print(round(tuition,2))

Explanation:

The first 2 lines initializes tuition and rate to 10000 and 0.04 respectively

tuition = 10000

rate = 0.04

The next line iterates from year 1 to year 14

for i in range(1,15):

This line calculates the tuition for each year

tuition = tuition + tuition * rate

The next 3 lines prints the tuition for year 1 to year 10

if i <= 10:

print("Year "+str(i)+" tuition:",end=" ")

print(round(tuition,2))

The next 3 lines prints the tuition at the 4th year after year 10 (i.e. year 14)

if i == 14:

print("Tuition 4th year after:",end=" ")

print(round(tuition,2))

#include using namespace std; int main( ) { const int NUM_ROWS = 2; const int NUM_COLS = 2; int milesTracker[NUM_ROWS][NUM_COLS]

VARVARA [1.3K]

Answer:

#include <iostream>

using namespace std;

int main()

{

const int NUM_ROWS = 2;

const int NUM_COLS = 2;

int milesTracker[NUM_ROWS][NUM_COLS];

int i = 0;

int j = 0;

int maxMiles = -99; // Assign with first element in milesTracker before loop

int minMiles = -99; // Assign with first element in milesTracker before loop

milesTracker[0][0] = -10;

milesTracker[0][1] = 20;

milesTracker[1][0] = 30;

milesTracker[1][1] = 40;

maxMiles = milesTracker[0][0];

minMiles = milesTracker[0][0];

for (i = 0; i < NUM_ROWS; i++){

for (j = 0; j < NUM_COLS; j++){

if (milesTracker[i][j] > maxMiles){

maxMiles = milesTracker[i][j];

}

if (milesTracker[i][j] < minMiles){

minMiles = milesTracker[i][j];

}

cout << "Min: " << minMiles << endl;

cout << "Max: " << maxMiles << endl;

return 0;

}

Explanation:

It seems you want to find the min and max value in the array. Let me go through what I added to your code.

Set the maxMiles and minMiles as the first element in milesTracker

Create a nested for loop that iterates through the milesTracker. Inside the loop, check if an element is greater than maxMiles, set it as maxMiles. If an element is smaller than minMiles, set it as minMiles.

When the loop is done, print the minMiles and maxMiles
