Question numbers subject to change
Use POSIX calls fork pipe dup2 and close to implement an autograding program. Capture the standardoutput of a child process into a pipe. The child process should exec the program ./test with no additional arguments (other than the process name). In the parent process read from the pipe: Exit the parent process as soon as the captured output contains the ! character. Before exiting the parent process send SIGKILL to the child process. Exit 0 if the output contained a !. Otherwise if the child process exits causing the pipe write end to be closed, then exit with a value of 1. Be sure to close the unused ends of the pipe in the parent and child process
