Answer:
<u>Explanation:</u>
An input statement using the input function at the shell prompt is as follows:
If a prompt asks for a input, a number is to be added
num = input ('Number: ')
num = num + 1
print(num)
Explanation of results: This gives error at line num= num + 1 as cannot convert int object to str implicitly
Let P(n) be "a postage of n cents can be formed using 5-cent and 17-cent stamps if n is greater than 63".Basis step: P(64) is true since 64 cents postage can be formed with one 5-cent and one 17-cent stamp.Inductive step: Assume that P(n) is true, that is, postage of n cents can be formed using 5-cent and 17-cent stamps. We will show how to form postage of n + 1 cents. By the inductive hypothesis postage of n cents can be formed using 5-cent and 17-cent stamps. If this included a 17-cent stamp, replace this 17-cent stamp with two 5-cent stamps to obtain n + 1 cents postage. Otherwise, only 5-cent stamps were used and n 65. Hence there are at least three 5-cent stamps forming n cents. Remove three of these 5-cent stamps and replace them with two 17-cent stamps to obtain n + 1 cents postage.Hence P(n + 1) is true.
Answer:
if(isalpha(passCode[0]))
{
passCode[0] = '_';
}
if(isalpha(passCode[1]))
{
passCode[1] = '_';
}
Explanation:
The first if statement uses isalpha() function which checks if the character passed in this function is an alphabet. If the character stored in 0-th position (which is the first position whose index is 0) of the variable passCode is an alphabet then it is replaced with the '_'
The next if statement checks if the second character in the passCode variable is an alphabet. This means the function isalpha() checks if the character stored in second position (index 1) of the variable passCode is an alphabet then it is replaced with the '_'
The complete activity with this chunk of code added and the output is attached in a screen shot.
The answer for this would be B.
Answer:
Transport mode
Explanation:
The host-to-host transport mode of internet protocol security (IPsec) is mostly used between two host devices or between a user and a server. When you go online and Google something, what you have done is send a packet request to a server. The IPsec’s transport mode offers secure protection to parts of this IP packet. The packet consists of the original IP header and an IP payload (TCP header and data). In transport mode, only the IP payload is encrypted. The original IP header is not.
