代码缩进

1.不同函数和类定义完后回车空开一行，以便观察函数

 1 class account
 2 {
 3      public:
 4           int id;
 5           double balance;
 6           double annualInterestRate;
 7 };
 8 
 9 double getMonthlyInterestRate(double x)
10 {
11     double y;
12     y=x/12;
13     return(y);
14 }
15 
16 int withDraw(int a)
17 {
18     a=-a;
19     return a;
20 }
21 
22 int deposit(int b)
23 {
24     return b;
25 }

2.不同操作：定义、申明、赋值、运算、函数调用。。。都应空开一行以便观察语句

 1 int main()
 2 {
 3     account acc;
 4     
 5     acc.id=1122;
 6     acc.balance=20000;
 7     acc.annualInterestRate=0.045;
 8     
 9     int with;
10     int depo;
11     double getMonthly;
12     
13     getMonthly=getMonthlyInterestRate(0.045);
14     with=withDraw(2500);
15     depo=deposit(3000);
16     
17     acc.balance=acc.balance+with+depo;
18     cout<<"余额："<<acc.balance<<'
';
19     cout<<"月利率："<<getMonthly<<'
';
20     
21     return 0;
22 }

3.若语句太长超出屏幕，应该回车对齐以便观察

a=monday+tuesday+a+b*567-
    trouble*7-90^4+your;

4.大括号左对齐，括号后空行并缩进4位

1 double getMonthlyInterestRate(double x)
2 {
3     double y;
4     y=x/12;
5     return(y);
6 }

5.头文件名称空一位
