You don't need a program to compare strings since std::string already provides support for all the comparison operators (<, <=, >, >=, == and !=).
To roll your own you must first create a string class and then provide operator overloads for the comparison operators. To compare strings, start at the first character in each string and compare. So long as they remain equal, move onto the next character. The comparison ends as soon as any character differs. You need only compare these two characters to decide which string is the lesser.
To perform a case insensitive comparison, copy the two characters and convert the copies to lower case (or upper case, it doesn't matter). Then compare the copies. Do this for each character as you compare them rather than converting the entire string.

What is cputs function in computer c plus plus?
Nothing.The C language only recognizes a few keywords, like "for" and "if". Most of what's in a C program ... that doesn't reference routines in the C program itself ... are library calls, and cputs() is one of those. What it does is write its argument (which should be a pointer to a character string) to the console... console put string.
