Question

Write a program that reads from stdin and filters out duplicate lines of input. It should read lines from stdin, and then print each unique line along with a count of how many times it appeared. Input is case-sensitive, so “hello” and “Hello” are not duplicates. There can be an arbitrary number of strings, of arbitrary length. Note that only adjacent duplicates count, so if the input were the lines “hello”, “world”, and “hello” again, all three would be treated as unique.

./uniq
hello
hello
hello
world
world
^D # close stdin
3 hello
2 world

./uniq
hello
world
hello
^D # close stdin
1 hello
1 world
1 hello

C Language:-

C was initially utilised for system development tasks, especially for the operating system's programmes. Because C produces code that executes almost as quickly as code expressed in assembly language, it was accepted as a system development language.
The most used computer language is C. Along with the Java programming language, which is also quite popular and is most commonly used by contemporary software programmers, it consistently ranks at the top of the popularity scale.
