Question

Define a function CoordTransform() that transforms its first two input parameters xVal and yVal into two output parameters xValNew and yValNew. The function returns void. The transformation is new = (old + 1) * 2. Ex: If xVal = 3 and yVal = 4, then xValNew is 8 and yValNew is 10.Sample program:#include using namespace std;int main() { int xValNew = 0; int yValNew = 0; CoordTransform(3, 4, xValNew, yValNew); cout << "(3, 4) becomes " << "(" << xValNew << ", " << yValNew << ")" << endl; return 0;}

Answer 1

Answer:

The following program is written in C++ Programming Language:

//header file

#include <iostream>

using namespace std; //using namespace

//set void type method

void CoordTransform (int xVal ,int yVal ,int& xValNew, int& yValNew) {

xValNew = (xVal +1) *2;

 //here is the code

yValNew = (yVal +1) *2;

 //

return;

}

//main method

int main() {

int xValNew = 0;

 // initialize integer type variable

int yValNew = 0;

 // initialize integer type variable

CoordTransform(3, 4, xValNew, yValNew);

 // method definition

// print result

cout << "(3, 4) becomes " << "(" << xValNew << ", " << yValNew << ")" << endl;

return 0;

 //return

}

Explanation:

In the following program, we can set the header file or using namespace.

Then, set void type function which is given in the question and write the following codes and close the function.

Then, set the main method, inside it, we initialize two integer type variable to 0.

Then, call the function and pass the value through the parameter.

Answer 2

Define a function CoordTransform() that transforms its first two input parameters xVal and yVal into two output parameters xValNew and yValNew is as shown as the code below

Explanation:

Define a function CoordTransform() that transforms its first two input parameters xVal and yVal into two output parameters xValNew and yValNew.

The function returns void. The transformation is new = (old + 1) * 2.

Ex: If xVal = 3 and yVal = 4, then xValNew is 8 and yValNew is 10.

Prints:

(3,4) outputs (8,10)

(0,0) outputs (2,2)

Sample program:

#include using namespace std;int main() { int xValNew = 0; int yValNew = 0; CoordTransform(3, 4, xValNew, yValNew); cout << "(3, 4) becomes " << "(" << xValNew << ", " << yValNew << ")" << endl; return 0;}

Answer:

#include <iostream>

using namespace std;

/ void CoordTransform(int *ptr1, int *ptr2);

int main()

{

  int xVal;

int yVal;

cout<<"please enter two valid integers";

cin>>xVal;

cin>>yVal;

CoordTransform(&xVal , &yVal);

int xValNew=xVal;

int yValNew=yVal;

cout<<xValNew<<yValNew;

  

  return 0;

}

void CoordTransform(int *ptr1, int *ptr2)

{

int a = *ptr1;

*ptr1=(*ptr1+1)*2;

*ptr2=(*ptr2+1)*2;

}

/

void CoordTransform (int xVal ,int yVal ,int& xValNew, int& yValNew) {

xValNew = (xVal +1) *2;

yValNew = (yVal +1) *2;

return;

}

int main() {

int xValNew = 0;

int yValNew = 0;

CoordTransform(3, 4, xValNew, yValNew);

cout << "(3, 4) becomes " << "(" << xValNew << ", " << yValNew << ")" << endl;

return 0;

}
