Question

So I am getting an error when I submit my c++ code. The prompt for the hw was as follows:

Create 2 functions:
1) Degrees2Radians: which has input Degrees, and returns Radians
2) Drawline: which takes two parameters: a character and numRepetitions and prints the character numRepetitions times, followed by a newline

Inside main()
For values between 0 and 360, in 5 degree increments:
calculate and print the value of sin (degrees),
After every 90 degrees, print out a line of 30 dashes (minus signs '-')

Extra information required:

#include <cmath> // for sin function

In order to have the precise format we want:
Put this at the top of main:

cout.setf(ios::fixed);
cout.setf(ios::showpoint); // show decimals even if not needed
cout.precision(5); // show 5 digits to right of decimal

My code:

#include <iostream>

#include <cmath>

using namespace std;

int i, j;

const double PI = 3.141592;

double Degrees2Radians()

{

int degree; // user input for degree

double radian; // to store the value of radians

// input from the user

cout << "Enter the value in degree: ";

cin >> degree;

// converting degrees into radians

radian = degree * (PI / 180);

return radian;

}

// this function will show the character numRepetitions times

void Drawline(char a, int numRepetitions)

{

// in this loop, character is displayed numRepetitions times

for (i = 1; i <= numRepetitions; i++)

cout << a << endl;

}

int main(void)

{

cout.setf(ios::fixed);

cout.setf(ios::showpoint);

cout.precision(5);

double radian; // to store the value of radians

// in this loop, the values for radians is

// displayed, after every 5 degrees

for (i = 0; i <= 360; i = i + 5)

{

// converting degrees into radians

radian = i * (PI / 180);

// display The result

cout << "sin " << (i) << " = " << sin(radian) << endl;

// in this if, a line of 30 dashes will be

// displayed, after every 90 degree

if (i % 90 == 0 && i > 0)

{

for (j = 0; j < 30; j++)

cout << "-";

cout << endl;

}

// calling the functions

Degrees2Radians();

Drawline('a', 5);

}

Below I have attached the error screenshots I received. It seems the bracket needs to be included after sin and then for sin(60),sin(130),sin(185),sin(215),sin(225),sin(255),sin(275)and sin(360) I am getting different results from what the output should be.
