Power Traversing in Array of pointers
Please find the below program. the requirement and description of the program also given:


Code:
ganesh@ubuntu:~/my_programs/c/letusc/chap9$ cat fa.c.old
/* Program : write a program to count the number of 'e' in thefollowing array of pointers to strings:

	char *s[] = {
			"We will teach you how to..",
			"Move a mountain",
			"Level a building",
			"Erase the past",
			"Make a million",
			"....all through C!"
		    };
*/

/* Date : 09-June-2010 */

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

int main(void)
{
        char *s[] = {
                        "We will teach you how to..",
                        "Move a mountain",
                        "Level a building",
                        "Erase the past",
                        "Make a million",
                        "....all through C!"
                    };
	int count=0;
	char *sptr;
	sptr=*s;

		while ( *sptr!='\0' ) {
			if (*sptr=='e') { ++count;}
	        	++(sptr);
		}
	printf("count of e's : %d\n", count); 
	return 0;
}

Output of the above program:

Code:
ganesh@ubuntu:~/my_programs/c/letusc/chap9$ gcc -o fa fa.c
ganesh@ubuntu:~/my_programs/c/letusc/chap9$ ./fa
count of e's : 2

It only counts the e's in first line. I know I have to traverse through rest of*s[]. But don't know how to do it. Can any one please help me in this?

Thanks in Advance,
Ramkrix

NAME

       sincosd(), sincosdf(), sincosdl(), sincosdw(), sincosdq() - functions that compute both sine and cosine of an argument specified in degrees

SYNOPSIS

DESCRIPTION

       These functions are available only for Integrity servers.

       stores the sine of x (x specified in degrees) in the object pointed to by sptr and stores the cosine of x in the object pointed to by cptr.

       is a version of it takes and arguments.

       is a version of it takes and arguments.

       is an version of it takes and arguments.

       is equivalent to on HP-UX systems.

       For more information, see the at the following site:

RETURN VALUE

       in the object pointed to by sptr and 1 in the object pointed to by cptr.

       If x stores NaN in the objects pointed to by its pointer arguments and raises the invalid exception.

       If x is NaN, stores NaN in the objects pointed to by its pointer arguments.

ERRORS

       No errors are defined.
