The instruction that should replace /* missing code */ so that the method countA works as intended is (e)  str = str.substring(pos+1);

<h3>Methods</h3>

The program is an illustration of methods (or functions)

Methods are blocks of program statements that are executed when called or evoked

For the method to return the number of character A in a string, the loop body must check if the current character is A.

This is done using the substring method of a string

The syntax of this is: str.substring(pos + 1).

Where str represents the string, and pos + 1 represents the character index

Hence, the missing instruction is str = str.substring(pos+1);

Write an expression that executes the loop while the user enters a number greater than or equal to 0.
LekaFEV [45]

Answer:

while (userNum >=0) {...}

Explanation:

In a <u>while loop</u>, <u>the loop is executed until the condition is false</u>.

Since the loop will execute while the user enters a number greater than or equal to 0 (and that number is declared as <em>userNum</em>), we need to check if <em>userNum</em> is greater than or equal to 0.

4. In this problem, we consider sending real-time voice from Host A to Host B over a packet-switchednetwork (VoIP). Host A conve
mina [271]

Answer:

The time elapsed is 0.017224 s

Solution:

As per the question:

Analog signal to digital bit stream conversion by Host A =64 kbps

Byte packets obtained by Host A = 56 bytes

Rate of transmission = 2 Mbps

Propagation delay = 10 ms = 0.01 s

Now,

Considering the packets' first bit, as its transmission is only after the generation of all the bits in the packet.

Time taken to generate and convert all the bits into digital signal is given by;

t = \frac{Total\ No.\ of\ packets}{A/D\ bit\ stream\ conversion}

t = \frac{56\times 8}{64\times 10^{3}}          (Since, 1 byte = 8 bits)

t = 7 ms = 0.007 s

Time Required for transmission of the packet, t':

t' = \frac{Total\ No.\ of\ packets}{Transmission\ rate}

t' = \frac{56\times 8}{2\times 10^{6}} = 2.24\times 10^{- 4} s

Now, the time elapse between the bit creation and its decoding is given by:

t + t'  + propagation delay= 0.007 + 2.24\times 10^{- 4} s + 0.01= 0.017224 s
