C Program to Compare Two Strings without using strcmp function In my opinion if you know a clever versions exists is enough (because in real life I would Google "efficient strstr implementation") if you happen to know the name even . The following diagram clearly illustrate the working principle of stricmp() inbuilt string . The only library function you call is printf(), . Since the function returned the pointer to the first occurrence of string "you", the substring of string str starting from "you" has been printed as output. If it founds substring in the base string . This is also defined inside the header file <string.h>, so we must include it first. Count Occurrences of a Substring in a String in C - QnA Plus First parameter must be a string whereas second parameter must be a character. putchar ():- Display output as a single character. ( you can generate all the sub string by recursion or iteration both) 2. check the occurrence of the the sub string in the string, If the string occur more then once print it ( for matching sub string many algorithm ava.
