Here, we have to create a strcmp (string compare) function that compares two string but ignores cases of the characters of the string. The function will return -1 if string1 < string2, 0 if string1 = string2, 1 if string1 > string2.Let’s take an example to understand the problem, Inputstring1 ... Read More
