Consider the following piece of C code running on UNIX:How many child processes are created when executing this
Step by step
Solved in 2 steps
- code this in RUBY programming languagePlease Answer in C++ only A Rajesh teaches a cooking class. The course is attended by NN students, numbered 11 to NN. The cook must participate in the presence before each class, i.e. call out the names of the students one by one and indicate which students are present. Each student has a first and last name. To save time, Rajesh only wants to call up students' first names. However, if there are multiple students with the same first name, the Rajesh must call out the full names (first and last names) of all those students. For any student who does not share a first name with any other student, the cook can still only call that student's first name. Help the Rajesh decide for each student whether to call that student's full name or just their first name.

The Elevator should be able to travel between five floors namely Ground, 1st, 2nd, 3rd, 4th and 5th floors. The elevator can travel going up (unless they are at the 5th floor) or going down (unless they are at the ground floor). The elevator can only containone passenger (which is the current user of the program). Initially the elevator begins and loads at the Ground Floor. If the user wants to travel to the 5th floor, the elevator shall go up to the saidfloor. It is the option of the user if they want to alight the elevator or not on the 5th floor or anyfloor on the way.Realistic rules should apply: If the user alights at the 4th floor, when they ride the elevator again, it should begin traveling from the 4th floor and from there choose to go up or down. It should have some validation,meaning, only the valid characters should be received by the program(G, 1, 2, 3, 4, 5).
