The function <u>strpos()</u> is a function in php that returns the position of the first occurrence of a particular substring in a string. Positions are counted from 0. The function receives two arguments. The first argument is the string from which the occurrence is to be checked. The second argument is the substring to be checked.
In this case, the string is "Get Well Soon!" while the substring is "Well"
Starting from 0, the substring "Well" can be found to begin at position 4 of the string "Get Well Soon!".
Therefore, the function strpos("Get Well Soon!", "Well") will return 4.
Then, with the echo statement, which is used for printing, value 4 will be printed as output of the code.

Answer: In operating system a code segment which accesses some shared variables or resources one at a time atomically such other no other code or process is accessing that resource or variable at the same time.
Entry section code block allows the access to the shared resource or variable and exit section code signals the termination from access to the shared resource or variable.
Explanation:
Entry and exit section codes needs to check certain properties before allowing the access and removal of access to a particular code segment.
These conditions are:
1. Bounded waiting.
2. Mutual exclusion.
3. checking thread execution status to allows other threads to enter the critical section (CS).
