Question

Design the logic for a program that allows a user to enter 20 numbers, then displays them in the reverse order of entry.

Design the logic for a program that allows a user to enter 20 numbers, then displays each number and its difference from the numeric average of the numbers entered.

The program is C++. I need a Pseudocode

Answer 1

Code (first one)

#include<iostream>
using namespace std;

int main()
{
    int a[20]; // create array of 20 elements
    for(int i=0;i<20;i++)
    {
        cin>>a[i];
    }
    cout<<"values in reversed order\n";
    for(int i=19;i>=0;i--)
    {
        cout<<a[i]<<" ";
    }
    return 0;
}

Pseudocode (first one)

• create array a with 20 elements.
• for i 0 to 20(20 exclusive) ,get user input and store input as a[i]
• for i 19 to 0(0 inclusive) print a[i]

Code(second one)

#include<iostream>
#include<cstdlib>
using namespace std;

int main()
{
    int a[20]; // create array of 20 elements
    for(int i=0;i<20;i++)
    {
        cin>>a[i];
    }
    int sum=0;
    for(int i=0;i<20;i++)
    {
        sum=sum+a[i];
    }
    cout<<"number and thier difference with avg\n";
    int avg=sum/20;
    for(int i=0;i<20;i++)
    {
        cout<<a[i]<<" "<<abs(a[i]-avg)<<"\n";
    }
    return 0;
}

Pseudocode

• create array a with 20 elements
• for i to 20 get user input and store it as a[i]
• sum=0
• for i to 20(20 exclusive), sum =sum+a[i]
• avg=sum/20
• for i to 20(20 exclusive), print a[i] abs(a[i]-avg)
