K&R C Exercise 1-1c: Reading gcc Error Messages

Exercise 1-1. Run the “hello, world” program on your system. Experiment with leaving out parts of the program to see what error messages you get. This page covers the error-experimentation part of Exercise 1-1. The baseline working program is in Exercise 1-1a. Here we deliberately break it five different ways — and more importantly, learn …

K&R C Exercise 1-1b: Experimenting with printf

Exercise 1-1. Run the “hello, world” program on your system. Experiment with leaving out parts of the program to see what error messages you get. This page covers the printf side of Exercise 1-1: what the format string actually does, how escape sequences work, and what happens when you modify or multiply printf calls. For …

K&R C Exercise 1-1a: The “hello, world” Program

Exercise 1-1. Run the “hello, world” program on your system. Experiment with leaving out parts of the program to see what error messages you get. This is the very first program in The C Programming Language by Kernighan and Ritchie — and for many people, the first C program they ever type. The exercise has …

N-Queens Problem in C – Backtracking Solution with All Solutions

The N-Queens problem asks: place N chess queens on an N×N board so that no two queens share a row, column, or diagonal. The standard C solution uses backtracking — place queens one row at a time, try every column in that row, recurse if the placement is safe, and undo (backtrack) if a dead …

Cyclic Rotation of Array in C – Left and Right Rotation with Example

A cyclic rotation of an array in C shifts every element one position to the left or right, with the element that falls off one end wrapping around to the other. A left rotation moves the first element to the last position; a right rotation moves the last element to the first position. This operation …
