GNG1106 Lecture 3 Final 2026 (GNG1106) – 220 Questions & Answers – C Data Types, Encoding, Operators & Math Library

This document contains approximately 220 expert-verified GNG1106 Lecture 3 2026 questions and answers covering C programming fundamentals including formatted input/output, numeric data representation, arithmetic operations, type promotion, and mathematical functions. It begins with conversion specifiers for printf and scanf, detailing correct format usage for short, int, long, unsigned types, float, double, and long double, as well as width and precision formatting rules. The material provides in-depth explanations of binary representation, bits and bytes (2⁸ = 256 configurations), natural binary encoding, fixed-point and floating-point encoding, and numeric ranges for one-byte and two-byte representations. It clearly distinguishes between signed and unsigned types, discusses literal values in C, scientific notation (e.g., 1.32e13), and explains floating-point types (float, double, long double) along with precision and range considerations. In addition, the document thoroughly examines arithmetic operators (+, −, *, /, %), fixed-point vs floating-point division behavior (e.g., 3/5 = 0 vs 3.0/5 = 0.6), operator precedence rules, parentheses evaluation order, unary operators, and modulus operations. It explains implicit type promotion, high-range and high-precision types, casting, symbolic constants using #define, the sizeof operator, and math library functions (sqrt, pow, exp, log, sin, cos, tan, ceil, floor, fabs, etc.) requiring #include math.h. The document also clarifies radian-based angle measurements and evaluates multiple example arithmetic expressions to reinforce understanding. This study resource is particularly relevant for: Students enrolled in GNG1106 Introduction to Programming Engineering students learning C programming Computer Engineering and Software Engineering majors First-year programming students preparing for midterms or finals Students needing strong foundations in numeric encoding and arithmetic logic It is suitable for courses such as: Introduction to Programming in C Engineering Computation Programming Fundamentals Computer Systems Basics Numerical Methods for Engineers This document functions as a comprehensive Lecture 3 exam preparation guide, reinforcing formatted I/O syntax, numeric encoding principles, arithmetic logic evaluation, type promotion rules, and C math library usage essential for foundational programming proficiency.
