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 simulator so it prints the exact main.cpp source, the g++ build command, the first_program executable, and the ./first_program run command in their correct order.

int main() {}
g++ main.cpp -o first_program
first_program
./first_program
