Thread: need help with pointers

the first function works (int length (char a[]), but the output to the second function is -28865. I need to use pointers and pointer arithmatic.

Code:

#include <stdio.h>
#include <string.h>

int length (char a[]);
int point_size (int *a);

int main()
{
char word[]="Trying this out";
int size;
int pointer_eh;

size = length (word);

printf("The length is %d\n", size);

printf("The length is %d", pointer_eh);


return 0;
}


int length (char a[])
{
	int i;
	int size=0;

        clrscr();

        for (i = 0; i != strlen(a); i++)
	{
		size++;
	}
	return(size);
}

int point_size (int *a)
{

	int i, pointer_eh;

	while (*a[i] != '\0')
	{
		*(a+1);
	 	i++;
	}
	return (pointer_eh);
}
