The format of a procedure

The prototype
```
type identifier (type1, type2, ...);
```
And the implementation.

type identifier (type param1, type param2, ...) {
    variable declarations;

    statements;
    return();
}

Please note, the number and value of parameters must match in
- Number
- Type

And the program should now have the form

/* block comment */
#include <files>

constant declarations

function prototype declarations

int main () {
   variable declarations

   statements;

   return(0);
}

function implementations

Some String functions
- length
  - size
  - New type (sort of )
  - string::size_type len;
  - Some code
- find
  - Locate a pattern within a string
  - Not found returns string::nopos
  - Find eather a char or a string
  - Some code
- substr
  - extracts a substring from a string
  - two parameteres, start postion and length.
  - If you give bad parameters, you have a problem.
  - Consider this code
Some math odds and ends
- autoinitialization
  - ```
  int a;
  a = 0;
  	   
```
- type identifier=value;
- Works for multiples.
- ```
int a = 5,
    b = 9;
	    
```
- Auto increment
  - i = i + 1;
  - Prefix
    - i++;
  - Postfix
    - ++i;
- Consider this code
