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<<'\n'; 19 cout<<"月利率："<<getMonthly<<'\n'; 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
