random collection of problems its a curated selection to cover various aspects of the language Exercises could be categorized into several key areas 2 Basic Syntax and Data Types Exercises focusing on variables data types operators and basic inputoutput operations form the foundation For instance a common exercise might involve calculating the area of a circle given the radius Control Structures Exercises on loops for while dowhile conditional statements ifelse and switch statements help understand program flow A practical example would be creating a program to check whether a number is prime Functions Exercises demonstrate function declaration definition and parameter passing An example involves developing a function to sort an array in ascending order Arrays and Strings Exercises dealing with array manipulation string handling eg character arrays and string functions are crucial for working with collections of data A realworld example would be a program to count the occurrences of each letter in a text file Pointers Exercises illustrate the use of pointers for memory manipulation A case study could be simulating dynamic memory allocation for a linked list Structures and Unions Exercises on custom data types emphasizing how to combine different data types into a single entity become increasingly important as programs grow in complexity Example Exercise Problem Write a C program to calculate the factorial of a given nonnegative integer C include long factorialint n if n int main float length width area printfEnter length and width scanff f length width area length width printfArea fn area return 0 Exercise 610 Conditional Statements Implement decisionmaking logic using if else if and else statements Example Determine if a number is positive negative or zero Exercise 1115 Loops Practice using for while and dowhile loops for iterative tasks Example Calculate the factorial of a number Exercise 1620 Arrays and Strings Work with arrays to store and manipulate data Example Find the maximum element in an array III Intermediate Exercises 2140 Data Structures and Algorithms These exercises introduce more complex data structures and algorithm concepts Exercise
