For loop with a mathemtical expression involved

For loop with a mathemtical expression involved

I am trying to utilize the Math.Cos() function in c# to print a range of of values from 0 to 2pi increasing by .1pi, so 20 iterations. The problem is I cannot get my x value to change as the for loop is executing.

I am trying to utilize the Math.Cos() function in c# to print a range of of values from 0 to 2pi increasing by .1pi, so 20 iterations. The problem is I cannot get my x value to change as the for loop is executing.

    public void Cos()
    {
        double x = 0;
        double a = Math.PI * x;
        double b = Math.Cos(a);

    for (int i = 0; i < 21; i++)
    {

        Console.WriteLine("Cos({0})pi = {1}", x, b);
        x += .1;

    }
}

When I print the results to the console, it only remembers the value of cos at x = 0. So I just get 1, 20 times as a result for Cos(.1)pi, Cos(.2)pi, etc...

C++ Tutorial - Loops In C++ [For Loop, While Loop, Do While Loop]

In this C++ Tutorials we are going to talk about Loops In C++, we are going to learn different C++ Loops like For Loop, While Loop and Do While Loop. There may be a situation, when you need to execute a block of code several number of times, using loops you can do these kind of functionalities. A loop statement allows us to execute a statement or group of statements multiple times. There are different types of loops that you can use in c++, for loop, while loop, do while loop, also there are different control statements like break and continue in c++ loops, using control statements we can change the execution of loops from its normal sequence.
