Advantages: 1. Code can be reused; 2. Code is relatively independent; 3. Easy division of labor

Programming: High Cohesion and low coupling

Function Definition and call. Example:

 1           //  Defines a maximum function.  2           Static   Int Max ( Int A, Int B) //  A and B are form parameters. function input 3   {  4               If (A> = B)  5   {  6                   Return A; //  If a> = B, the returned value is.  7   }  8               Else  9                  Return B; //  If a <B, the return value is B.  10   }  11   12           Static   Void Main ( String  [] Arge)  13   {  14               //  Call a function  15              Int A = 3 , B = 6 , C = 1 , D = 4  ;  16               Int Z = max (a, B), c), d ); //  A, B, C, and D are real parameters (actual parameters)  17   Console. writeline (z );  18   19 }
