Head A C # Chinese version chapter II page66

Start coding the real job of any program is to write instruction statements. But the statement does not exist in a vacuum. So we started digging into it and writing code. Create a new Form Application project.

Add a directive statement to display a message to start by double-clicking the first button. Then add the following six instruction statements to the Button1_Click () method. Look at the code closely and see its output.

Syntax 101

*每行代码都是分号结尾
x=x+1；
*注释以双斜线开始
//this line is ignored
*大多数空格都无所谓
x = 3；与x=3；一样
*变量声明时都有类型和名字（第四章你会学习很多的类型）
int weight;
//weight is an integer
*类和方法定义时都有大括号
public void go()
{
//amazing code here
}
