What is an example of syntax in programming?
When referring to a programming language, the syntax is a set of rules for grammar and spelling. In other words, it means using character structures that a computer can interpret. For example, if a user tries to execute a command without proper syntax, it generates a syntax error, usually causing the program to fail.

Why was programming in ENIAC so cumbersome?
ENIAC is the acronym for Electrical Numerical Integrator And Calculator, a 30-ton monstrosity that contained over 20,000 vacuum tubes and covered 1800 square feet of a room. The programming was cumbersome because after calculations were performed, it took weeks to reprogram ENIAC and hard drive data recovery was virtually non-existent.
