The function strcmp() is a built-in library function and it is declared in “string. … It compares strings lexicographically which means it compares both the strings character by character. It starts comparing the very first character of strings until the characters of both strings are equal or NULL character is found.

Can you write a program to compare two strings without using the strcmp () function?
