Introduction to Programming Lecture No. 1

Program “A precise sequence of steps to solve a particular problem”

Critical Skills – Analysis – Critical Thinking – Attention to Detail

Design Recipe To design a program properly, we must: – Analyze a problem statement, typically expressed as a word problem expressed as a word problem – Express its essence, abstractly and with examples examples –Formulate statements and comments in a precise language precise language –Evaluate and revise the activities in light of checks and tests checks and tests

– PAY ATTENTION TO DETAIL – These skills are useful for anybody anybody – All assignments in this course should follow the these should follow the these guidelines guidelines

Computers are STUPID

Humans are even more…….
