Suppose we write the following code (pseudo-code) on our shell terminal: while (1){ char *cmd-get_cmd) int p fork ); exec(cmd); printf("My pid is: %d", p); else waitpid p); Let's execute the code above. What do you observe and why? Suggest two solutions (changes) to this code to achieve improved performance. Each solution should involve only one change in the code presented above. No line of code should be entirely removed
