Geometry

Question

I am stuck on this assignment where it asks me to make it so I enter the size of the geometric figure and it calculates the area of the figure. This is the code I used:

string kind = Console.ReadLine();
if (kind="square")
{
double a = double.Parse(Console.ReadLine());
double squareS = a * a;
Console.WriteLine(squareS);
}
if (kind = "rectangle")
{
double a = double.Parse(Console.ReadLine());
double b = double.Parse(Console.ReadLine());
double rectangleS = a * b;
Console.WriteLine(rectangleS);
}
if (kind = "circle")
{
double r = double.Parse(Console.ReadLine());
double circleS = r * r*Math.PI;
Console.WriteLine(circleS);
}
if (kind = "triangle")
{
double a = double.Parse(Console.ReadLine());
double h = double.Parse(Console.ReadLine());
double triangleS = a*h/2;
Console.WriteLine(triangleS);
}

and its giving me this error which I cannot fix: Cannot implicitly convert type 'string' to 'bool'. Can anyone help please?

Answer 1

= is an assignment operator.
== is an comparison operator.

Answer 2

Use .Equals() method when comparing one string to another. Avoid use of equality operator for comparing string contents.

You were assigning new value for <kind> when using assignment operator `=`
