Question

Complete the following program skeleton. When finished, the program will ask the user for a length (in inches), convert that value to centimeters, and display the result. You are to write the function convert. (Note: 1 inch = 2.54 cm. Do not modify function main.)

#include #include using namespace std;// Write your function prototype here.int main(){ double measurement; cout ≪ "Enter a length in inches, and I will convert\n"; cout ≪ "it to centimeters: "; cin ≫ measurement; convert(&measurement); cout ≪ fixed ≪ setprecision(4); cout ≪ "Value in centimeters: " ≪ measurement ≪ endl; return 0;}

//

// Write the function convert here.

//

Answer 1

Convert function definition:

The following code defines the function convert. It accepts one double parameter and returns their measurement value.

• This function takes a double argument.

• Convert 1 inch is equal to 2.54cm.

// Write the function convert here.

void convert(double *measurement)

{

// calculate the measurement

*measurement = *measurement*2.54;

}

Complete program is as follows:

The following program demonstrates the functionality of the function convert():

Program:

#include

 

#include

 

using namespace std;

 

void convert(double*);

 

int main()

 

{

    

    double measurement;

    

    cout << "Enter a length in inches, and i will convert\n";

    

    cout << "it to centimeters:";

    

    cin >> measurement;

    

    convert(&measurement);

    

    cout << fixed << setprecision(4);

    

    cout << "Value in centimeters:" << measurement

    

    << endl;

    

    return 0;

    

}

 

// Write the function convert here.

 

void convert(double *measurement)

 

{

    

    // calculate the measurement

    

    *measurement = *measurement*2.54;

    

}

Sample Output:

Enter a length in inches, and i will convert

it to centimeters:45

Value in centimeters:114.3000
