Your declaration and definitions are not the same.

void pop(int[], int&); // note the &
int push(int[],int&,int); // note the &

void pop(int st[],int top){ // note the lack of &
int push(int st[],int top,int info){ // note the lack of &

JEEEEEE.

hate it when I make those silly mistakes. Life would be easier if compilers were a little more specific.

If you want more specific compilers, program in java :p
