Ex2+T2+Question+2

Yesterday I found out this code. I want to know in general what it is used for. Also when trying to compile it there were several error. Find all the errors and correct the code so it can be used. int 4a; put an integer number in variable "a" float b; a real number up to 7 digits into variable "b" Double d 3 = 0; d3 variable is asigned to d3 String s; alphanumerical digits into variable "s" (as long as your RAM memory can hold), is saved. char c; alphanumerical digits into variable "c" (1 out of the 255 possible characters), is saved 4a = Int.Parse(textBox1.Text); variable "4a" is a text, the code is going to it is going to be changed into a number so that it can work as an integer number b = Float.Int32(Label1); variable "b" is going to be converted into a number (7 dgits number) and is going to be showed in label1 if (a>b) then; If a is bigger than b than next code will make its function. d3 = 4a%b; the variable d3 is going to be 4a%b if ( d3=0 ); if d3 is equal to 0 than next code will happen. TextBox = d 3+ b; the text box will have the value d3 plus variable b else if the opperation is not posible the, next code will happen. MessaBox.Show = "No es....."+b; it is going to be showed that "No es..... plus b variable. else if the opperation is not posible, the next code will happen. if(4a=B) if 4a is equal to B, the next code will happen. MessageBox.Show = "Obvio el número es...."; It is going to show a text, else if the opperation is not posible is used Else= If i t doesn't happen, the next will. MessageBox.Show = "DUH, el problema con tus números es que....."; It is going to be shown the text on the message box. c = Int.Parse32(Textbox): The variable c is saved and converted from number to text in order to be shown. s = a+b+'hola'; The variable c is saved with the text "hola"
