This is a scratch drill — your code runs, nothing is graded or recorded. No test cases, no expected output, no verdict.

TASK

Process the pushes 4, 2, 7, and 1 using an int pointer, size, and capacity. Allocate a larger array only when size equals capacity, copy the existing elements, delete the old array, append the new value, and print the vector state after each push.

OUTPUT

Sample

size=2 capacity=2 values=4 2
size=3 capacity=4 values=4 2 7
size=4 capacity=4 values=4 2 7 1

AI TUTORTalk to tutor

Scoped to Vector Implementation - 1. The tutor can see the reading, its checkpoints and your drill code.

The tutor reads this lesson alongside you and answers questions about it — nudging you towards the answer rather than handing it over.

The tutor will not answer a quiz question for you, and it will not paste a working drill. It explains the reading it can see.
