yes you are right.. So if I include the statement that you used to get the count of n then combination of you and me will make this program even better- right?
Code:
# 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,i=0;
size_t n = (sizeof s/sizeof(char *))-1;
while ( n >=0) {
   if (*((s[n])+i++)=='e') { ++count;}
    else
 if(*((s[n])+i)=='\0'){
  n--;i=0;}
}
printf("count of e's : %d\n",count);
return 0;
}

Code tags please.

elf32_fsize

elf32_fsize(3ELF)					       ELF Library Functions						 elf32_fsize(3ELF)

NAME

       elf32_fsize, elf64_fsize - return the size of an object file type

SYNOPSIS

       cc [ flag ... ] file ... -lelf [ library ... ]
       #include <libelf.h>

       size_t elf32_fsize(Elf_Type type, size_t count, unsigned ver);

       size_t elf64_fsize(Elf_Type type, size_t count, unsigned ver);

DESCRIPTION

       elf32_fsize() gives the size in bytes of the 32-bit file representation of count data objects with the given type. The library uses version
       ver to calculate the size. See elf(3ELF) and elf_version(3ELF).

       Constant values are available for the sizes of fundamental types:

	      Elf_Type	File Size Memory Size
	      ELF_T_ADDR     ELF32_FSZ_ADDR sizeof(Elf32_Addr)
	      ELF_T_BYTE     1	  sizeof(unsigned char)
	      ELF_T_HALF     ELF32_FSZ_HALF sizeof(Elf32_Half)
	      ELT_T_OFF ELF32_FSZ_OFF  sizeof(Elf32_Off)
	      ELF_T_SWORD    ELF32_FSZ_SWORD	 sizeof(Elf32_Sword)
	      ELF_T_WORD     ELF32_FSZ_WORD sizeof(Elf32_Word)

       elf32_fsize() returns 0 if the value of type or ver is unknown. See elf32_xlatetof(3ELF) for a list of the type values.

       For the 64-bit class, replace 32 with 64 as appropriate.
