Introduction to C Programming

Overview
The 5 day Introduction to C Programming class is designed to give your Programming staff a good understanding of the C Language as it relates to the z/TPF. The course is a mix of lectures and practical exercises where students can reinforce the knowledge gained in the lecture sessions. This class is specifically targeted to the z/TPF environment.

Pre-Requisites
Prior computer programming experience in either high level or assembly languages, and an understanding of structured programming techniques.

Audience
Programmers who are required to write programs in the C Language.

Student Numbers
The maximum recommended student to instructor ratio is 12:1

Objectives
On completion of the syllabus students will be able, with the aid of course notes, to:

· Write, compile, test and execute C Programs.
· Declare and update variables using standard data types, structures and arrays.
· Control the logic and flow of a C program.
· Write functions that accept arguments and pointers to arguments.
· Write programs using the C run time library.
· Identify common programming errors.
