Question

How do I use pointers again in C ???

Answer 1

can u be more specific?

Answer 2

I think first you create the pointer like this :

struct element{
int n;
struct element *next;
};
typedef struct element ele;

Then in your program whenever you need an instance from this pointer you just create it as follow :
ele *P; //P is the name of the new pointer.

Answer 3

well that's the implementation of linked lists

Answer 4

Yep, but it uses pointers, so it's an example.

Answer 5

like in main for example

void velocity( &&&& )
{
int x;
get the x and y velocity;
}

void printanswer ( ^^^^^ )
{

}

main()
{
CODE;
}

How could I point the value or address(I honestly do not have an idea for I do not understand it)from one void function to another void function?

Shall I change it into a int function and type return at the end?
But how?

My goal is to calculate something and simply call the headers in main.

like
main()
{
velocity();
printanswer();
}

Also where should I put the *x, or the x or the &x?
And how should I use them?
I am really quite confused.

MEDALS will be awarded for the best answerS that I will get. xD

Answer 6

#include <stdio.h>

int main(void)
{
char ch = 'c';
char *chptr = &ch;

int i = 20;
int *intptr = &i;

float f = 1.20000;
float *fptr = &f;

char *ptr = "I am a string";

printf("\n [%c], [%d], [%f], [%c], [%s]\n", *chptr, *intptr, *fptr, *ptr, ptr);

return 0;
}
