how to sort alphabetically

Question

Hello, I am working with C/C++ and I wanted to know if there is a simple way to be able to compare two strings and know which of the two comes first in the alphabet

Answer 1

If you are using C++ then std::string class objects have relational operators overloaded accordingly so that you can simply treat them as any other objects while performing comparison between 2 of them.

If you are using C then strcmp () is what you might be looking for.

If the main motive of comparing 2 strings lexicographically is to sort a collection of them then as YUGRAJ said, there are factory function for those defined in bot C and C++ standard libraries.

std::sort () in C++
qsort () in C

Answer 2

Do you mean to sort a collection of strings, or compare two strings to see which one was lexicographically greater?

Answer 3

Yeah simple sort function on string array Or vector will do that it will give you lexicographically sorted value
