Write it, run it, read the output

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

TASK

Complete the C++ program so it prints the n = 4 centered solid star pyramid exactly, with three leading spaces and one star on row 1, then two leading spaces and three stars, one leading space and five stars, and seven stars on row 4. Do not print an extra space or blank line.
