anyone can explain it to me plz
int.Parse height = int.height ;

45,831 PointsYou are given a string of heightInput with a value that has been put in by someone, but it's a string. To convert this string into an integer data type, you use the Parse() method, which is a static method of the int class. You can pass the string into the parenthesis and the return value will be an integer, which can be assigned to the newly declared integer named height, all in one line. A string can't take math operations, that's why the conversion is needed.
int height = int.Parse(heightInput);

45,831 PointsAt the start of the challenge, heightInput is of type string, it's a string. The goal is to convert it to an integer type of variable. So, declare a new variable of type int, and name it height. Then, assign the value of this new variable, of type int, to be the value returned from using the Parse() method of the int wrapper class. You can call this method by the dot operator on the int class. No object is needed, it's a static method of the wrapper class named int. You should pass in the string identified as heightInput into the parenthesis of the Parse() method of the int wrapper class. Static methods do not require creation of an object, the class name can invoke the method. In this case the class name is int. The returned value is assigned to be the value of the new variable you declared, and good news, the two types match!

Anyway to summarize the video, int.Parse is a function that will return an integer version of a string passed in to it. To solve this task you have to create an int variable called height in the same way you normally would. And then set it equal to the int.Parse method with the heightInput variable as the argument. Like this:
string heightInput = "168";
int height = int.Parse(heightInput);

45,831 PointsThe left side of your equation should only be a declaration of existence, an empty new variable to contain something of your choice. Then use assignment, the equals sign, to say what its value should be. Parsing input will return a value on the right side of the equals, and as long as both sides are of the same type of data, the assignment will be accepted.
