C Program to demonstrate how the escape characters work.Escape character is the single character, and it is compiled as the character constant.Escape characters are used to solve the c format problems.An escape sequence is denoted by using the backslash () as an escape character, followed by a single character indicating the nonprintable character desired.Read more …
Finding the position of a substring means locating the index where one string first appears inside another — for example, “world” starts at index 6 in “hello world”. This is one of the most common string operations in C, used for parsing text, validating input, and implementing search features. The standard library already provides strstr() …
Write a C program to demonstrate the recursive function.Recursion is the programming technique that a process invoking itself again and again. In this program, We reverse the given number and checks it is a palindrome or not.

Write a C program to count the leaves of the binary tree.Binary tree is the ordered directed tree data structure, in which each node has at most two nodes.A node is called as a leaf node, if it does not contains any child elements. In this program, We used the structures to create the binary …
A hash table maps keys to storage slots in near-constant time: run the key through a hash function, take the result modulo the table size, and that’s the index where the key lives. It’s the data structure behind Python dicts, Java HashMaps, and database indexes — and one of the most-asked interview topics in C, …
Chapter 1: A Tutorial Introduction is where K&R C begins — and it moves faster than most C books. By exercise 1-8 you are counting characters by category; by 1-13 you are drawing histograms; by 1-22 you are folding long lines. The chapter uses only a tiny subset of C deliberately: loops, if/else, basic functions, …
