Write a C++ program that calculates the value of the series sin z and cos z, sin 2r or cos 2z where the user enters the value of r (in degrees) and n the number of terms in the series. For example, if n 5, the program should calculate the sum of 5 terms in the series for a given values of r. The program should use switch statements to determine the choice sin r and cos z, sin 2r or cos 2a. (Note: you may have to convert 7 Points degrees to radians for sin and cos functions). b.

Explanation / Answer
The following code in C++ gives you the required code for given nested if-else flow chart:
#include<iostream>
using namespace std;
int main()
{
char grade;
int weight,bin,t,s,a;
if(grade=='A')
{
if(weight>35)
{
bin = 1;
}
else
{
t = s + a;
}
}
else
{
//..bunch of statements
}
return 0;
}
Hope it helps, do give your valuable response.
