Answer:

public static void display(int [] arr){

System.out.print("Arrays: ");

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

System.out.print(arr[i]+" ");

}

}

System.out.println();

}

public static int displaySum (int [] arr){

}

return sum;

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

sum+=arr[i];

}

float average = sum/arr.length;

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

if(arr[i]>average){

System.out.print(arr[i]+" ");

}

System.out.println();

}

Explanation:

The methods were written in Java. See attachment for explanation where I used comments to explain each lines.

An acronym is a word formed by taking the first letters of the words in a phrase and making a word from them. For example, AGH i

gregori [183]

Answer:

Here is the Python program:

#the method acronym that takes an argument phrase

def acronym(phrases):

acronym = "" #to store acronym of a phrase

#loop to split the input phrase and return its acronym in upper case letters

for phrase in phrases.split():

acronym = acronym + phrase[0].upper()

return acronym

#main function that takes input phrase from user and display its acronym

def main():

phrases = input("Enter a phrase: ")

print("The acronym for your phrase is ",acronym(phrases))

main()

Explanation:

First let me explain the method acronym. This method takes a parameter phrase to return its corresponding acronym. First the phrase is split using split() method which is used to return the list of words in a phrase. For loop is used that will keep splitting the words in the string (phrase) entered by the user.

In this statement: acronym = acronym + phrase[0].upper() the acronym is computed. phrase[0] means the first character of each word in the phrase which is found out by the split() method is converted to upper case by using upper() function and then stored in acronym variable. Each time the acronym is found and its first character is converted to upper case and added to the acronym variable.

Then the main() function prompts the user to enter a phrase and then calls the acronym function and passed that phrase as parameter to that function. Then the computed acronym for the phrase is printed on the screen.

Write a program that: Takes the list lotsOfNumbers and uses a loop to find the sum of all of the odd numbers in the list (hint:

Alika [10]

Answer:

Following are the code to this question:

#include <iostream>//defining header file

using namespace std;

int main()//defining main method

{

int x[]={2,3,4,6,7,8,9,1,11,12};//defining 1-D array and assign value

int i,sum=0;//defining integer variable

for(i=0;i<10;i++)//defining loop for count value

{

if(x[i]%2==1)//defining if block to check odd value

{

sum=sum+x[i];//add value in sum variable

}

cout<<sum;//print sum

return 0;

}

Output:

Explanation:

In the above-given program, an integer array "x" is declared that holds some integer values, and in the next line two integer variable "i and sum" is defined which is used to calculate the value.

In the next line, a for loop is declared, that counts all array value, and it uses the if block to check the odd value and add all the value into the sum variable.

c++ Consider this data sequence: "3 11 5 5 5 2 4 6 6 7 3 -8". Any value that is the same as the immediately preceding value is c

Ksivusya [100]

Answer:

int fNumber,scndNumber = -1, 

dup = 0; 

do { 

cin >> fNumber; 

if ( scndNumber == -1) { 

scndNumber = fNumber; 

} 

else { 

if ( scndNumber == fNumber ) 

duplicates++; 

else 

scndNumber = fNumber; 

} 

} while(fNumber > 0 ); 

cout << dup; 

Explanation:

Here three variables are declared to hold the first number which is used obtain all the inputs given by the user, second number to hold the value of last encountered number and “dup” variable to count the number of duplicate values.

“Do-while” loop help us to get the input check whether it is same as previous input if yes then it adds to the duplicate value otherwise the new previous value if stored.
