C Program to generate Graph using grphics.h

C Program to Generate the graph sheet using the grphics.h library. To use graphics.h, we have to install the drivers in to the the system by using the initgraph() function. Here  we derive the graph of input sizes verses time taken for input sizes. x axis represents inputs(0,10000,20000,—-), y axis rep time(0,0.05,0.1,0.15—). Read more about …

K&R C Exercise 1-19: Reverse a String in C

Exercise 1-19. Write a function reverse(s) that reverses the character string s. Use it to write a program that reverses its input a line at a time. Approach The core algorithm is the classic two-pointer swap: place one index at the start of the string (i = 0) and one at the end (j = …

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 …
