Write the code to compute and output how many times the value 99 is found in an array of integers named numbers

Thank you for being the rare question where you actually provide what language you want your answer in; I approve, and encourage this.

In Java, the following will work.
I made it a bit more versatile to work with others numbers, other than 99, if you so please (if not, just hardcode the 99 in yourself).

// Example list - fill this with numbers yourself.
ArrayList<Integer> nums = new ArrayList<>();
int n = 99;
int count = (int)nums.stream().filter(i -> i == n).count();
System.out.println(n + " occurences.");

Lorico [155]

Answer:

Hi there! Please find the answer below.

Explanation:

The program below demonstrates how each of the requirements can be coded in a simple Python script. To copy the array, we can use the copy() method of the array. To calculate the diff, we can use a few different techniques, so I have implemented it using a loop over the arrays and just storing and displaying the difference in the 2 arrays.

new_string.py

def add_test_score(score):

test_score.append(score);

contact_hash = {}

test_score = []

print("Enter 5 test scores: ");

for x in range(0, 5):

input_string = input("Enter test score " + str(x + 1) + ": ")

add_test_score(int(input_string));

print(test_score);

test_score_copy = test_score.copy();

for e in test_score_copy:

if e < 60:

test_score_copy[test_score_copy.index(e)] += 10;

diff = [];

for e in test_score:

print(test_score[test_score.index(e)]);

print(test_score_copy[test_score.index(e)]);

if not test_score[test_score.index(e)] == test_score_copy[test_score.index(e)]:

diff.append(e);

print(diff);

1| def saveUserProfile(firstName, lastName, age, height, country):

Feliz [49]

Answer:

Joyner

David

USA

1.8

Explanation:

def saveUserProfile(firstName, lastName, age, height, country):

This is the definition of function named saveUserProfile which accepts the following parameters:

firstName
lastName
age
height
country

filename = lastName + firstName + ".txt"

When the file is created it will be named as the lastName and firstName string combined with .txt as extension. For example if the lastName contains the name string Joyner and firstName contains the name David then the file created to be written is named as JoynerDavid.txt

outputFile = open(filename, "w")

This statement uses open() method in write mode and uses outputFile object to access the file. "w" represents write mode i.e. file is opened in write mode to write on it.

a) Joyner is written on line 1 of that file because of the following statement of above function:

print(lastName, file = outputFile)

This statement prints the string stored in lastName i.e. Joyner. Here outputFile opens the file in "w" write mode and writes the last name to the first line of the file.

b) David is written on line 2 of that file because of the following statement of above function:

print(firstName, file = outputFile)

This statement prints the string stored in firstName i.e. David. Here outputFile opens the file in "w" write mode and writes the first name to the second line of the file.

c) USA is written on line 3 of that file because of the following statement of above function:

print(country, file = outputFile)

This statement prints the data stored in country i.e. USA. Here outputFile opens the file in "w" write mode and writes the country name to the third line of the file.

d) 1.8 is written on line 4 of that file because of the following statement of above function:

print(height, file = outputFile)

This statement prints the value stored in height i.e. 1.8. Here outputFile opens the file in "w" write mode and writes the height value to the fourth line of the file.

e) 30 is written on line 5 of that file because of the following statement of above function:

print(age, file = outputFile)

This statement prints the value stored in age parameter of function saveUserProfile i.e. 30. Here outputFile opens the file in "w" write mode and writes the age value to the fifth line of the file.

Write a loop that fills an array int values[10] with ten random numbers between 1 and 100. Write code for two nested loops that

zalisa [80]

Answer:

#include <iostream>

#include <cstdlib>

using namespace std;

int main() {

int[] array = new int[10];

int index = 0;

while(index < array.size()){

int number = (rand() % 100) + 1;

for (int i = 0; i < 1; i++) {

array[index] = number;

cout<< "Position "<< index << "of the array = "<< number << endl;

++index;

}

Explanation:

The while loop in the source code loops over a set of code ten times, The for loop only loops once to add the generated random number between 1 and 100 to the array of size 10. At the end of the for loop, the index location and the item of the array is printed out on the screen. The random number is generated from the 'rand()' function of the C++ standard library.
