Matching parentheses. An math expression may have a number of parentheses like (, ), [, ], { and }. Each openning parenthesis (, or [, or { must be macthed by a corresponding closing parenthsis ), or ] or }. For example, 12 { 34 / [ 6 * ( 55 - 10 ) / ( 100 20 ) ] } has matched pairs of parentheses, while 12 { 34 / ( 6 * ) ] } does not. Write a function to check whether an input math expression has matched parentheses. The header of the function is given as follows:
bool match( const char exp [ ], const int s);
The input math express is store in the char array exp, and the size of exp is s. It returns true if all parentheses are matched or false otherwise.

The deposit method  uses an if statement to check if the amount to be deposited is negative. If so, it does nothing, but returns False signifying that the transaction failed.

However, if the test finds out that the amount to deposit is positive or zero, the deposit method increments the balance, then returns True, signifying a successful transaction.

The withdraw method is similar, but this time, it tests if the amount to be withdrawn is greater than the available balance. If so, it ignores the transaction, and returns False.

If the withdrawal amount is less or equal to the available balance, the withdraw method decrements the available balance, then returns True, signifying a successful transaction.

The type of system software that manages memory is an operating system. To manage memory, the operating system employs a number of software strategies.

The most crucial piece of software that runs on a computer is the operating system. It controls the memory, operations, software, and hardware of the computer.

You can converse with the computer using this method even if you don't understand its language. Memory connections are the structures that come before and after all memory areas, whether they are allocated or available.

Working memory, short-term memory, and long-term memory are the three primary categories of memory. While long-term memory stores your enduring memories, working memory and short-term memory enable you to retain and use transient information.

Therefore, an operating system is a sort of system software that controls memory.

Answer:

B, C, B

Explanation:

According to my understanding of these questions, these are in Java.

For the first one, there is a built in function called .length() for a string, so it's answer B.

For the second one, this should come out as C, 0 since compareTo compares the ascii values of the characters.

The third one's answer should be B. s1.equals(s2) for characters that are caps and not caps comes out with false, so ! would negate it. s1.equalsIgnoreCase(s2) would come out as true, ignoring the cases of APPLE.
