Question

Given the following C program, rewrite the program and use C++ header files, C++ constants, inline functions and C++ I/O. Please note that the standard C++ library header file, which defines the I/O functions is named <iostream>. This header file contains the definition of the std namespace.

/* Convert this program into a C++ program. */

#include <stdio.h>

#include <conio.h>

#define PI 3.141592

float reactance(float c,float f)

{

return 1/(2*PI*f*c);

}

int main()

{

float frq,cap,xc;

printf("Enter frequency => ");

scanf("%f",&frq);

   printf("Enter capacitance => ");

scanf("%f",&cap);

   xc=reactance(cap,frq);

printf("XC=%.2f Ohm",xc);

getch();

   return 0;

}

Answer 1

solution:

code:

include <iostream>

using namespace std;

const float PI=3.141592;

inline float reactance(float c,float f)

{

return 1/(2*PI*f*c);

}

int main()

{

float frq,cap,xc;

cout<<"Enter frequency => ";

cin>>frq;

cout<<"Enter capacitance => ";

cin>>cap;

xc=reactance(cap,frq);

cout<<"XC="<<xc<<" Ohm"<<endl;
return 0;

}

OUTPUT:

Enter frequency => 58.36
Enter capacitance => 2.1
XC=0.00129863 Ohm
