Elma had already worked with functions and objects, but she

repeated similar loops for searching, sorting, and filtering different

data collections. She found the materials on templates, containers,

iterators, and algorithms useful because the topics were presented

through compact, connected examples.

“I began identifying the data operation first, then choosing

the container and the way to express it.”

Rick already understood foundational syntax, but he often

duplicated code and lost track of the logic between functions when

writing longer programs. The ordered modules, parameter examples,

and assignments that divided one task into several connected

parts were particularly useful to him.

“The materials helped me see where one program

responsibility ends and another begins.”
