Course Description

C is a general purpose language with standards specified by the American National Standards Institute (ANSI). This course covers the fundamentals of C including working with data types, variables, and operators. It also demonstrates how to implement program flow using conditional statements and branching.
In this course, the instructor uses some non-standard Microsoft extensions. In these instances, the instructor uses quotes around the library names rather than the standard symbols.

Learning Objectives

C Basics

  • start the course
  • describe the characteristics of ANSI C, describe C tokens, and describe and step through the structure of a C program
  • write a simple program in C
  • compile a C program and execute it and describe the associated files

Data Types

  • describe and use fundamental data types and qualifiers in C
  • describe data types introduced in C99 including bool, and demonstrate how to use bool
  • describe implicit and explicit type conversion and implement type conversion in C


  • describe constants and use numeric constants in C
  • use character and string constants and represent integers with character constants in C
  • use escape character constant escape values and symbolic constants in C programs
  • use enumeration constants in C programs


  • describe and use variables in C programs
  • describe variable scope for C programs, blocks, nested blocks, and functions


  • describe operators and expressions and implement arithmetic operators in C programs
  • implement relational operators in C programs
  • implement logical operators in C programs
  • implement assignment, increment, and decrement operators in C programs
  • implement bitwise operators in C programs

Conditional Statements and Branching

  • describe and use if statements including nested statements in C programs
  • describe and use if-else statements in C program
  • use nested if-else statements in C programs
  • use the switch statements with case values in a C program and review the rules for switch statements
  • use the C conditional operator ?: in C programs
  • use goto for unconditional branching in C programs and describe issues with it
