I am trying to execute the pop function but my pop function is not working.
I run pop and then show and it is printing only 0
typedef struct Stack
{
int top;
int elements[20];
}
stack;
stack s;
void pop()
{
s.top--;
}
void show()
{
while(s.top>=0)
{
printf("%d\n",s.elements[s.top]);
s.top--;
}
}
The function
void pop()
has a void return type. So it is not returning an object for you to print.
pop
function should be
int pop()
{
if(s.top == -1) // -1 is delimiter for stack to be empty
{
printf("Stack is empty\n");
return -1;
}
return s.elements[s.top--];
}
