    linked list function test

    Im working on putting a link list together and I've removed all the code that isn't relevant..I have lots of cases to add but I'm getting errors on the add_last function(which places a new record at the end of the list) the errors say I have declaration syntax error at the first line of the function(add_last)...If you have any suggestions I would love to see them.. thanks


    Code:
    #include <stdlib.h>
    #include <ctype.h>
    #include <string.h>
    #include <stdio.h>
    #include <conio.h>
    
    typedef struct master
    {
    	char	 name[20];
    	float	expense;
    	struct master *p_next;
    
    }MASTER;
    
    
    void intro(void);
    char ragain(void);
    void signoff(void);
    void pause(void);
    MASTER* populate(void);
    MASTER* space(void);
    MASTER* add_last(MASTER *p_current,MASTER *p_newest);
    
    int main(void)
    {
    	int      choice=1;
    	char  	input = 'y';
    	MASTER 	*p_first;
    	MASTER 	*p_current;
    	MASTER 	*p_newest;
    
    	clrscr();
    	intro();
    
    	while(input == 'Y' || input == 'y')
    	{
    		p_first=populate();
    		p_current=p_first;
    
    		while(choice!=2)
    		{
    			clrscr();
    			puts("\nPlease enter a number from the menu choices and press <enter>.");
    			
    			puts("1. Add a new record to the end of the list.\n");
    			/*puts("3. Insert a new record into the list.\n");
    			puts("4. Delete a record from the list.\n");*/
    			puts("2. Exit the program.\n");
    			scanf("%d",&choice);
    
    			switch(choice)
    			{
    			
    
    				case 1: /*2*/
    				p_newest=populate();

    	pause();
    
    	return 0;

    while(choice!=2)
    {
    You're missing your matching closing braces.

    Hope is the first step on the road to disappointment.
