Answer to Question #233124 in C++ for alex

Question

Implement a C++ function which, when given the length of a simple pendulum in meters,

returns the period of oscillation in seconds, i.e.

period of oscillation = 2 π (length / g)

where Standard Gravity, g = 9.80665 metres/sec2

Implement a main function which reads the pendulum length, calls the above function and

prints the result. A pendulum of length 1 meter has a period of 2.006409 seconds.

Answer 1

#define _USE_MATH_DEFINES
#include <iostream>
#include <math.h>
using namespace std;


double func(double length){
    double g=9.80665;
    double period=2*M_PI*(sqrt(length / g));
    
    return period;
}
int main()
{
    double length;
    cout<<"\nEnter length: ";
    cin>>length;
    cout<<"\nPeriod of oscillation= "<<func(length);
    return 0;
}

Output
