Introduction to programming in C

From GCD to loops

This 55-lecture NPTEL course introduces programming in C through worked problems. Its opening lecture covers the process of programming, and tracing a simple program comes early, with the GCD algorithm as an example.

Problem-led topics

• Variables and operators.
• While loops and do-while loops, with examples such as GCD.
• A longest increasing subsequence problem worked across three lectures.
• Nested loops applied to a matrix problem, followed by for loops.

The lecture list reads as a sequence of problems rather than a catalogue of syntax, which suits learners who like to reason through code step by step.
