Declaration: char *strrchr(const char *s, int c); It scans a string s in the reverse direction, looking for a specific character c. Example: #include <string.h> #include <stdio.h> int main(void) { char text[] = "I learn through IndiaBIX.com"; char *ptr, c = 'i'; ptr = strrchr(text, c); if (ptr) printf("The position of '%c' is: %d\n", c, ptr-text); else printf("The character was not found\n"); return 0; } Output: The position of 'i' is: 19
