CIT Syllabus:
Students should:

Understand the meaning of problem solving and appreciate the use of a systematic
approach to solve problems;

Be able to apply concepts of systematic problem solving to real life problems;

Be aware of a brief historical development of the programming languages and
understand the differences between a high level

programming language and a low level programming language;

Understand the differences among the different translators: the compiler, the interpreter
and the assembler;

Understand the meaning of an algorithm and a program flowchart;

Be able to identify the objectives of an algorithm from an examination of its program
flowchart;

Appreciate that there are different ways of solving the same problem, and be able to
make simple comparison among them;

Be able to trace the logical flow, identify the values of variables during execution and
debug logical errors in segments of a program flowchart, or other means of realising the
solution of a problem;

