40%

Assuming the situation is that 2 cars park in these spots, what is the probably that they park next to one another, then the answer is indeed 40%. There are 20 different possible scenarios (5 spots for the first car to park in, times 4 for the second car). If the first car parks on either end (2/5 chance), then there is a 1/4 chance that the second car will park next to the first. If the first car parks in the middle 3 spots (3/5 chance), there is a 2/4 chance that the second car will park next to the first. The combined probability for the cars parking next to each other is (2/5 * 1/4 + 3/5 * 2/4 = 8/20 = 40%).

do the math

I hate to say it but the program will not compile as written. Try it and see. You get a mess of errors because "<<" gets interpreted as the left shift operator instead of the insert into stream operator. To get it to compile you have to use parenthesis like this: cout << (a&b) << (a|b) << (a&&b) << (a||b); In which case we see that the first and second expressions are the "bitwise and" and "bitwise or" operators while the third and fourth expressions are the "logical and" and "logical or" operators. the result is: 1711

use pointer solution to mark start, end of each word, do not use any additional memory

1) first reverse the entire string in place, which results in the spaces and words being in the right place for the final result, but each word is backwards 2) scan thru the string again and reverse each word in place.

just be prepared for one good shell script dealing with c file functions

While this question asked to manipulate the lowercase letters only, the hiring manager expects the uppercase letters to be manipulate too. So, the answer they expect is not the one that answers the question posed.

That question is crystal clear. Obviously the uppercase letters will need to be manipulated as well.

I remeber the smart pointer is a class with a pointer member which points to the actual object and a counter member to record how many pointers point to the object. If the number of the counter is 0, then call the destructor function to delete the object. This smart pointer is to provent dangle pointer.

TCP is connection oriented with many more checking mechanisms used to ensure message delivery and completeness , UDP has minimal checking, does not maintain a connection or ensure completeness or delivery of message.
