K&R C Chapter 6 Exercise Solutions — Structures

Chapter 6: Structures introduces struct, typedef, and self-referential structures (linked lists, binary trees). The chapter builds a word-frequency counter using a binary tree, then extends it with a hash table. Exercise 6-3 adds a cross-reference listing; 6-6 implements a rudimentary #define processor using a hash table — the most complex exercise in this chapter. These …

Day of the Week from a Date of Birth in C

Problem Statement Write a C program to find the day of the week from a date of birth. For example, given 02/04/2017 (2nd April 2017), the program should tell you it was a Sunday. The Approach Pick a base year whose January 1st is a known weekday. We use 1900 (Jan 1, 1900 was a …

C program to demonstrate assert macro.

Write a C program to demonstrate assert macro.assert macro defined in assert.h library. assert is mainly used for debugging. assert function checks the conditions at run time, and program executes only if the assert is true otherwise program aborts and shows the error message.Read more about C Programming Language . and read the C Programming …

C program to implement SJF algorithm.

Write a C program to implement SJF algorithm.Shortest Job First(SJF) is the CPU scheduling algorithm. In SJF, if the CPU is available it allocates the process which has smallest burst time, if the two process are same burst time it uses FCFS algorithm.Read more about C Programming Language . and read the C Programming Language …

FCFS Scheduling in C – First Come First Served CPU Algorithm

First Come First Served (FCFS) is the simplest CPU scheduling algorithm used by an operating system — processes are executed strictly in the order they arrive, with no interruption once a process starts running. It works exactly like a queue at a ticket counter: whoever arrives first gets served first, and everyone else waits their …
