Nid Help in my Programming (turbo C).... i nid help.... geniuses!!!

I need help in this turbo C codes of mine..(puros ni functions) ....i hope makatabang pud mo nako kay nag-labad na gyud ako ulo ani sigeg huna2x .... I hope butangan ninyu ug mga comments nano error ug nano sayup..... para makasabot pud kog maayu!!!Â* i don't know why errors come up with this functions..... so here they are....


#define MAX 100
#define LEN 50


typedef char elementtype[MAX][LEN];
typedef struct
{
elementtype data;
int top;
}Stack;
Stack S;


char *reverse_string(char str1[])
{
Stack *stemp;
char *temp;
int n;
initialize(stemp);

Â* for(n=strlen(str1)-1;n>=0;n- -)
Â* Â*{
Â* Â*push(str1[n] , stemp); //Error: cannot convert 'int' to 'char'Â*
Â* Â*}

return *(stemp->data);
}

void initialize(Stack *S) // this function does intitialize my structure to 0... basta "starting place ni"
{
S->top=MAX;
}

void push(char ch, Stack *S) //this function just would push characters into my Stack... basta i-sulod ang akong mga data
{
Â* if(S->top!=0)
Â* Â*{
Â* Â* S->top--;
Â* Â* S->data[S->top] = ch; // Error: Lvalue required daw ingun ang computer? wa ko kasabot...Â* Â*
//Error: Typemismatch pud..... str daw....

// Ngari gyud ko nga point wala kasabot..... mura dli man mo-accept ang computer saÂ* Â*
// akong mga statements specially ang pag assign nako sa 'ch'......Â* Â*
Â* Â*}
Â* else printf("Warning: StacK is Full!!!");
}




I'm waiting and hoping sa inyung mga comments....... kahibaw ko makatabang na sa akong skwela...^_^ TY da-an....

typedef char elementtype[MAX][LEN]; < ----- This is an array of string
typedef struct
{
elementtype data; <-----So this is an array of string also.You must assign a string (i.e. char *str, char str[])
to this data
int top;
}Stack;

S->data[S->top] = ch; // Error: Lvalue required daw ingun ang computer? wa ko kasabot... <-------

About this
typedef char elementtype[MAX][LEN];
elementtype data;

Are you trying to have a stack for characters? Or stack for strings?

Try to compare the one you assigned....

Problem:

S->data[S->top] = ch; --->You assign a character value to a double dimensional array of characters variable which is the
equivalent of single dimensional array of strings. So meaning the error exist coz you
assign a char data to an array of string which is wrong.

Solution:

a)
If this program is for stack of characters:

typedef char elementtype[MAX];

This is the correct assignment
S->data[S->top] = ch;
b)
But, if this program is for stack of strings

S->data[S->top] = ch; --> revise this assignment for example, S->data[S->top][Another Counter] = ch

Or

S->data[S->top] = string; --> Assign this variable to a string data type (i.e. char *str, char str[])


So is your stack has maximum limit??
