2 likes11,227 views
This document contains 15 programming problems and their solutions in C language from Chapter 1 of the book "Solution Programming in ANSI C" by Balagurusamy. The problems cover basic C programming concepts like input/output, arithmetic operations, conditional statements, loops, functions, arrays and structures. Each problem is presented with the coding, inputs provided, and expected output. The problems increase in complexity from simple text printing to calculating area of shapes to solving equations.
