How is a most recent variable different from a fixed variable

1 answer:

7 0

In this program, there are three variables: data, count, and value. In the first loop, a user is requested to enter the number of values to be later processed in the second loop. This number is requested repeatedly until the user gives a positive value. The variable data is used to store the latest input read, and there is no possibility for the program to guess what values the user will enter.

The variable value is used similarly in the second loop: it stores the latest input, and there is no known relation between its successive values.

The variable count, however, behaves very differently. Once it has been initialized its future values will be known exactly: it will step downwards one by one until it reaches its limiting value, i.e. zero.

In the following the variables data and value are said to have the role most-recent holder (as they store the latest value in some value succession - user input in this case), and the variable count is said to be a stepper. These roles occur in programs again and again. In fact, only ten roles are needed to cover 99 % of all variables in novice-level programs.

Create a stored procedure sp_Q1 that takes two country names like 'Japan' or 'USA'as two inputs and returns two independent sets

Zigmanuir [339]

Answer:

Check the explanation

Explanation:

CREATE PROCEDURE sp_Q1

"at"country1 NVARCHAR(15),

"at"country2 NVARCHAR(15)

BEGIN

SELECT SupplierID, CompanyName, Phone, Country FROM suppliers

where Country in ("at"country1,"at"country2)

SELECT ProductID, ProductName, UnitPrice, SupplierID FROM Products

where SupplierID in(

SELECT SupplierID FROM suppliers

where Country in ("at"country1,"at"country2)) ORDER BY SupplierID

END

-- Testing script.

DECLARE "at"RC int

DECLARE "at"country1 nvarchar(15)

DECLARE "at"country2 nvarchar(15)

-- Set parameter values here.

set "at"country1='UK'

set "at"country2='Canada'

EXECUTE "at"RC = [dbo].[sp_Q1]

"at"country1

,"at"country2

Kindly check the attached images below to see how it looks like on a code editor.

// PrintStrings // Traverse the 2D character array "strings" and print each of the contained strings.// See the example outputs

anzhelika [568]

Answer:

C++.

Explanation:

void printStrings(char strings[NUM_STRINGS][STRING_LENGTH]) {

// Multi dimension array can be traversed through multi-level loops

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

for (int j = 0; j < STRING_LENGTH; j++) {

cout<<"<<strings[i][j]<<";

}

cout<<endl;

}

Output would be like this, depending on the size of NUM_STRINGS;

"One"

"Two"

"Three"

Design a class that has an array of floating-point numbers. The constructor should accept an integer argument and dynamically al

attashe74 [19]

Answer:

See explaination for the code

Explanation:

Here is the code

class NumberArray

{

private:

float *aptr; // Pointer to the array

int arraySize; // Holds the array size

float max,min,avg;

public:

NumberArray(int); // Constructor

~NumberArray(); // Destructor

int size() const // Returns the array size

{ return arraySize; }

void storeNumber(float num,int ele);

float retrieveNumber(int ele);

float getHighest();

float getLowest();

float getAverage();

};

//*******************************************************

// Constructor for IntArray class. Sets the size of the *

// array and allocates memory for it. *

//*******************************************************

NumberArray::NumberArray(int s)

{

arraySize = s;

aptr = new float [s];

for (int count = 0; count < arraySize; count++)

*(aptr + count) = 0;

}

//******************************************************

// Destructor for IntArray class. *

//******************************************************

NumberArray::~NumberArray()

{

if (arraySize > 0)

delete [] aptr;

}

void NumberArray::storeNumber(float num,int ele)

{

if(ele<arraySize)

*(aptr+ele)=num;

}

float NumberArray::retrieveNumber(int ele)

{

return *(aptr+ele);

}

float NumberArray::getHighest()

{

float high=*(aptr+0);

for(int i=1;i<arraySize;i++)

if(high<*(aptr+i))

high=*(aptr+i);

return high;

}

float NumberArray::getLowest()

{

float low=*(aptr+0);

for(int i=1;i<arraySize;i++)

if(low>*(aptr+i))

low=*(aptr+i);

return low;

}

float NumberArray:: getAverage()

{

float ag=0;

for(int i=1;i<arraySize;i++)

ag+=*(aptr+i);

ag=ag/arraySize;

return ag;

}

//Header file section
