Write the character counting function using pointers in C programming?

Answer 1

What characters do you want to count? As I am not a mind-reader, I can only give you an example which might give you an idea.

size_t count_specified_char_occurances (const char *s, int c)

{

const char *p= s-1;

size_t count= 0;

while (*++p) if (*p==(char)c) ++count;

return count;

}

int main (void)

{

printf ("P in APPLE: %d\n", (int)count_specified_char_occurances ("APPLE", 'P');

return 0;

}
