Answer:

hii

Explanation

syntax error: a syntax error is an error in the syntax of a sequence of characters or tokens that is intended to be written in compile-time. A program will not compile until all syntax errors are corrected.

logic error: logic error is a bug in a program that causes it to operate incorrectly, but not to terminate abnormally. A logic error produces unintended or undesired output or other behaviour, although it may not immediately be recognized as such.

A blood bank maintains two tables - DONOR, with information about people who are willing to donate blood and ACCEPTOR, with info

Kipish [7]

Answer:

The sql query is given below.

Since we need to count of males and females for a particular blood group, we put xxx for the blood group.

SELECT COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "M%") as Male_Donors,

COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "F%") as Female_Donors

FROM DONOR

WHERE BG = xxx;

Explanation:

The clauses in the query are as follows.

1. SELECT: all the columns required in the output are put in this clause.

2. FROM JOIN ON: the table(s) from which the above columns are taken are put in this clause.

3. WHERE: any condition required to filter the output is put in this clause.

The query is explained below.

1. Find the number of male donors. Number of anything can be found using COUNT() function. A query is required since gender is included in deciding the type of donor.

2. The query is defined to find number of male donors as follows.

COUNT( SELECT DID FROM DONOR WHERE GENDER LIKE "M%"; )

3. In the previous query, LIKE operator is used since it is not defined what value is stored for male donors.

4. Similarly, the query to find the number of female donors is formed.

COUNT( SELECT DID FROM DONOR WHERE GENDER LIKE "F%"; )

5. Next, the final query is formed as follows.

SELECT: both COUNT() functions will come here.

FROM: table name

WHERE: specific blood group will be put here

GROUP BY: this clause is optional and is not used in this query.

HAVING: this clause is optional and is not used in this query.

6. The query after putting all clauses is shown below.

SELECT COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "M%"),

COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "F%")

FROM DONOR

WHERE BG = xxx;

7. Alias is used in the above query for each column to get the final query.

SELECT COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "M%") as Male_Donors, COUNT(SELECT DID FROM DONOR WHERE GENDER LIKE "F%") as Female_Donors

FROM DONOR

WHERE BG = xxx;

Write a program that asks the user to input an integer named numDoubles. Create a dynamic array that can store numDoubles double

Hitman42 [59]

Answer:

Answered in C++

#include <iostream>

using namespace std;

int main() {

int size;

cout<<"Length of array: ";

cin >> size;

double *numDoubles = new double[size];

double sum =0;

cout<<"Array Elements: ";

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

cin>>numDoubles[i];

sum += numDoubles[i];

}

delete [] numDoubles;

cout<<"Average: "<<sum/size;

return 0;

}

Explanation:

This line declares the size (or length) of the array

int size;

This line prompts the user for the array length

cout<<"Length of array: ";

This gets the input from the user

cin >> size;

This dynamically declares the array as of double datatype

double *numDoubles = new double[size];

This declares and initializes sum to 0

double sum =0;

This prompts the user for elements of the array

cout<<"Array Elements: ";

The following iteration gets input from the user and also calculates the sum of the array elements

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

cin>>numDoubles[i];

sum += numDoubles[i];

}

This deletes the array

delete [] myarray;

This calculates and prints the average of the array

cout<<"Average: "<<sum/size;

When Kim was working in her Microsoft® Excel® spreadsheet, she accidentally placed her book on the spacebar and erased the conte

zaharov [31]

Answer:

The undo tool.

Explanation:

Microsoft Excel is a spreadsheet application developed by Microsoft, it is used for analysing data. It's worksheets are made up of columns and rows or fields and records.

There are different ways of entering data to a cell. Click on the cell and type the data, copy and paste to the target cell, double-click on the cell to correct data and click on a cell and press the spacebar key to clear the data.

Excel records the action of event, so when a mistake is made like deleting a crucial cell data value, the undo tool is used to recover the data, since it holds records of events. The redo tool is the reverse of the undo tool.
