char to char*?

Hello, sorry if I'm asking a lot of questions, but is there any way to convert a char to char*?

I'm reading a string one by one, and if i find a certain character i want to push it to a stack, however my stack contains a char*.. how do i do this? :\

Code:

while(*x!='\0')
    {
        if(*x=='(')
		{
			char* temp = *x;
            push(&(*top),temp);
		}
..

obviously this doesn't work..neither does this

Code:

 if(*x=='(')
{
	char* temp;
	strcpy(temp,*x);
        push(&(*top),temp);
}

I tried this, but i'm not sure if its correct?

Code:

  if(*x=='(')
{
	char temp[2] ="(";
	char *p = temp;

       push(&(*top),p);
}

You cannot really "convert" a char * to a char, since a char * is a pointer to a value, and a char is a value itself. But you can assign the value pointed to by a char * to a char, or vice versa convert a char * to point to a value of another char.

Code:

char *a;
char b = 'c';

a = &b; /* A now points to b */
*a = b; /* Put the value of b in whatever a is pointing to */

Also &(*top) does not make any sense, since you are first dereferencing a pointer and then taking the address with the &-operator, so they cancel out. &(*top) is the same as just top.
