Question

Write a program that calculates voltage from current and resistance values.

Write the calcVolts() function (prototype, header, body) using pointers.

#include <iostream>
#include <iomanip>
using namespace std;

int main()
{

const int max_num = 10;
int k;

double current[max_num], resistance[max_num], calc_volts[max_num];

for (k = 0; k < max_num; k++ )
{

cout << "Please Enter the ten values given for resistance:";
cin >> current[k];

cout << "Now enter ten values for the resistance: ";
cin >> resistance[k];
}

for (k = 0; k < max_num; k++ )
{
calc_volts[k] = current[k] * resistance[k];
}

cout << " Current Resistance Volts" << endl;

for (k = 0; k< max_num; k++ )
{
cout << setw(7) << current[k] << setw(11) << resistance[k]
<< setw(11) << calc_volts[k] << endl;
}
}

Explanation / Answer

#include<iostream>

#include<array>

#include<stdio.h>

using namespace std;

void calcVolts(float*, float*, float*);

int main()

{

array<float, 10> voltage;

float cur[5]{10.62, 14.89, 13.21, 16.55, 18.62 };

float res[5]{ 15.3,3.0, 5.4, 2.9, 4.8};

printf("Current x Resistance = Voltage ");

calcVolts(cur,res,voltage);

}

void calcVolts(float *cu,float *re,float *vo)

{

for (int i=0; i!=5; ++i)

{

vo[i]=cu[i]*re[i];

printf("%4f %8f %13f ", cu[i], re[i], vo[i]);

}

}
