To describe data structures Learning Outcomes: After successful completion of this course, students will be able to: Understand various data types, operators, library functions, Input/Output operations. Decision making and branching and looping. Use Arrays, Characters, and strings. Understand user-defined functions, and recursive functions. Storage class of Variables Apply Pointers and Structure Pre-processors: Macro substitution, macro with argument File inclusion in C, I/O operations on files. SYLLABUS OF DSE-2A UNIT I (6 hours) History and importance of C. Components, basic structure programming, character set, C tokens, Keywords and Identifiers and execution of a C program. Data types: Basic data types, Enumerated data types, derived data types. Constants and variables: declaration and assignment of variables, Symbolic Constants, overflow and underflow of data. UNIT II (9 hours) Expressions and I/O functions Operators and Expressions: Arithmetic, relational, logical, assignment, increment/decrement and conditional operators, precedence of operators in an expression. Managing input and output from the standard devices. UNIT III (12 hours) Branching and Arrays Decision making and branching - if…else, nesting of if…else, else if ladder, switch. Looping in C: for, while, do…while, jumps in and out of loops. Arrays: Declaration and initialization of one-dim and two-dim arrays. Character arrays and strings: Declaring and initializing string variables, reading and writing strings from Terminal (using scanf and printf only). UNIT IV (9 hours) Functions and Storage class User- defined functions: definition of functions, return values and their types, function prototypes and calls. Category of Functions and recursive function. Passing arrays to functions, Storage class of Variables. UNIT V (9 hours) Pointers, Macros and Files Pointers: Declaration and initialization of pointer variables, accessing the address of a variable, accessing a variable through its pointer, pointer expressions, pointer increments/decrement and scale factor. Pointers and arrays, functions returning pointers. Introduction of structure. Pre-processors: Macro substitution, macro with argument, file inclusion in C. Defining and opening a file (only r, w and a modes), closing a file, I/O operations on files-fscanf and fprintf functions. PRACTICAL/LAB WORK – 30 Hours List of Practicals: 1. Roots of a quadratic equation (with imaginary roots also) 2. Sorting of an array and hence finding median 3. Mean, Median and Mode of a Grouped Frequency Data
