In this C program we will compare two strings using strcmp() fuction. The Strings will be given by the User.color>

strcmp() function compares two strings in this program, if two strings are identical (i.e: "Hello" and "Hello" are identical), then the function returns a integer value Zero "0" else, it returns a non-zero value.
If it returns -1 then it means, the first mis-match occured between a Higher-case and a Lower-case value.(i.e: Apple and apple)
If it returns +1 then it means, the first mis-match occured between a Lower-case and a Higher-case value.(i.e: apple and Apple)
Obviously the function strcmp() is case-sensitive.
strcmp() takes two arguements.
Like : strcmp(string1,string2);
