K&R C Exercise 2-7 — invert(x, p, n) Exercise 2-7: Write a function invert(x,p,n) that returns x with the n bits that begin at position p inverted (i.e., 1 changed to 0 and vice versa), leaving the others unchanged. Approach XOR is the natural bit-flip operator: b ^ 1 = ~b and b ^ 0 …
C Program to add two polynomials using structures. Structure is a c composite data type, in which we can define all the data types under the same name or object. Size of the Structure is the size of all data types, plus any internal padding. the key word “struct” is used to declare the structure. …
Exercise 2-1. Write a program to determine the ranges of char, short, int, and long variables, both signed and unsigned, by printing appropriate values from standard headers and by direct computation. Harder if you compute them: determine the ranges of the various floating-point types. Approach The exercise splits neatly into two halves. The straightforward half …
Data structures using C,Priority QUEUE is a abstract data type in which the objects are inserted with respect to certain priority. In this program, we created the simple ascending order priority queue, here items are inserted in ascending order.

Data structures using C, Stack is a data structure in which the objects are arranged in a non linear order. In stack, elements are aded or deleted from only one end, i.e. top of the stack. In this program, we implement the two stacks using the single array. Read more about C Programming Language . …
Exercise 1-23. Write a program to remove all comments from a C program. Don’t forget to handle quoted strings and character constants properly. C comments don’t nest. Approach The core challenge is that the same character sequence means completely different things depending on context. A /* inside a string literal is not a comment. A …
