Who develop punch card​

Computers and Technology
1 answer:
monitta3 years ago
7 0

Explanation:

The standard punch card (for computers) was invented and developed by Herman Hollerith. But the idea of punch cards was already long invented, used to control Jacquard looms.

Jacquard looms were looms that used punch cards to control the pattern a loom weaves.

The idea of punch cards in Jacquard looms also influenced Charles Babbage, who decided to use punched cards to control the sequence of computations in his proposed analytical engine. Unlike Hollerith's cards of 50 years later, which were handled in decks like playing cards, Babbage's punched cards were to be strung together.

Answer:

The algorithm:

Input days

sum = 0

for i = 1 to days

   input text

   sum = sum + text

end for

average = sum/days

print average

The program in pascal:

var days, sum, text, i:integer;

var average : real;

Begin

    write ('Days: '); readln(days);

    sum:=0;

    for i := 1 to days do begin

         write ('Text: ');  readln(text);  

         sum:=sum+text;

    end;

    average := (sum/days);

    writeln ('The average text is' , average);

End.

Explanation:

This declares all variables

var days, sum, text, i:integer;

var average : real;

This begins the program

Begin

This gets the number of days from the user

    write ('Days: '); readln(days);

Initialize sum to 0

    sum:=0;

This iterates through the days

    for i := 1 to days do begin

This gets the text for each day

         write ('Text: ');   readln(text);  

This sums up the texts

         sum:=sum+text;

End loop

    end;

Calculate average

    average := (sum/days);

Print average

    writeln ('The average text is' , average);

End program

End.

myrzilka [38]

Answer:

import java.util.Scanner;

public class Sales

{

public static void main(String[] args) {

   

    int sum;

    Scanner input = new Scanner(System.in);

   

    System.out.print("Enter number of salespeople: ");

    int salespeople = input.nextInt();

    int[] sales = new int[salespeople];

       

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

    {

     System.out.print("Enter sales for salesperson " + (i+1) + ": ");

     sales[i] = input.nextInt();

    }

    System.out.println("\nSalesperson   Sales");

    System.out.println("--------------------");

    sum = 0;

       int maxSale = sales[0];

       int minSale  = sales[0];

       int minId=1;

       int maxId=1;

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

    {

               System.out.println("     " + (i+1) + "         " + sales[i]);

 sum += sales[i];

  if(maxSale < sales[i])

           {

               maxSale = sales[i];

               maxId = i+1;

           }

           if(minSale > sales[i])

           {

               minSale = sales[i];

               minId = i+1;

           }

   }

System.out.println("Total sales: " + sum);

       System.out.println("The average sale is: " + sum / salespeople );

       System.out.println("Salesperson "+ maxId + " had the highest sale with "+ maxSale + ".");

       System.out.println("Salesperson "+ minId + " had the lowest sale with "+ minSale + ".");

       

       int amount = 0;

       int counter = 0;

       System.out.print("Enter an amount: ");

       amount = input.nextInt();

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

    {

     if(sales[i] > amount) {

         counter++;

         System.out.println("Salesperson "+ (i+1) + " exceeded given amount. (Number of sales: " + sales[i] +")");

     }

    }

       System.out.println("Number of salespeople exceeded given amount is: "+ counter);

}

}

Explanation:

- Ask the user for the number of salesperson

- According to entered number, create an array called sales to hold sale number for each person

- In the first for loop, assign the given sales numbers

-  In the second for loop, print all the sales people with sales, calculate the total sales. Also, find the minimum and maximum sales numbers with associated individuals.

- Print total, average, highest, and lowest sales.

- Ask user enter an amount

- In the third for loop, find the sales people who exceeded this amount.

- Print number of sales people who exceeded the amount.
