Programming with C, 5 Days

The course is aimed at developers' not familiar C program development. This course covers all aspects of Programming with C. The course teaches the design, writing and testing of C programs. Many exercises are performed by the developer to ensure that the statements taught are fully understood and practical experience is gained.

Pre-requisites

Knowledge of the host environment is required (either OS/390 or Windows).

Course Objectives

Whilst covering the basics of C programming and how it is used, this course also aims to give an insight into structuring C programs, C verbs, manipulating data,using functions and testing C programs.

On completion of this course the student will be able to:

• Develop Structured C Programs
• Understand and Use C Verbs
• Develop C programs using the available verbs
• Develop and use C Functions
• Develop and Test C programs accessing different types of files

Course Environment

Development will be performed using either:

IBM Mainframe
Visual C++ running on a Windows platform

Course Format

Practical sessions make up a large part of the course, allowing delegates to demonstrate and reinforce the lectures given. During these sessions the delegate will gain experience of writing and testing different types of C programs using the various C verbs available.

Examples are used extensively, ranging from simple code snippets to full applications with complete ‘real world’ functionality. These are supplied at the start of the course and it is encouraged that the delegates execute and ‘experiment’ with these under the instructor’s guidance as they are introduced.

These examples are available to take away, along with the delegate’s own work.

The comprehensive Student Guide supplied is fully indexed serving as a useful reference tool long after the course has finished. Delegates will also be able to access a free help-line with technical questions relating to topics covered on the course.
