a)

Explanation of Solution

“atoi” function:

In C++, the predefined function “atoi” is used to convert a string value into an integer value; it passes a string literal or character array as an argument and it converts the received value into an integer value; it takes only one parameter as an argument.

  • If the argument value contains nonconvertible contents combined with the integer value then the values will be ignored while converting.
  • In same way, the function will return “0” when the values can’t be able to convert into double data type.

Syntax:

The syntax for the “atoi” function is as follows:

int atoi (const char* n);

In the above statement,

  • “int” represents the return type of the function...

b)

Explanation of Solution

“atol” function:

In C++, the predefined function “atol” is used to convert a string value into a long integer value; it passes a string literal or character array as an argument and it converts the received value into a long integer value; it takes only one parameter as an argument.

  • If the argument value contains nonconvertible contents combined with the integer value then the values will be ignored while converting.
  • In same way, the function will return “0” when the values can’t be able to convert into double data type.

Syntax:

Syntax for “atol” function is as follows:

long int atol (const char* n);

In the above statement,

  • “long int” represents the return type of the function...

c)

Explanation of Solution

“atof” function:

In C++, the predefined function “atof” is used to convert a string value into a double-precision floating point value; it passes a string literal or character array as an argument and it converts the received value into a double type value; it takes only one parameter as an argument.

  • If the argument value contains nonconvertible contents combined with the integer value then the values will be ignored while converting.
  • In same way, the function will return “0” when the values can’t be able to convert into double data type.

Syntax:

Syntax for the “atof” function is as follows:

double atof (const char* n);

In the above statement,

  • “double” represents the return type of the function...

d)

Explanation of Solution

“itoa” function:

In C++, the predefined function “atof” is used to convert an integer value into a string literal; it contains three parameters to refer the integer to convert, pointer character to store the result, and base number to convert.

Note: It is a deprecated item in C++; so many C++ compilers are not supporting this function.

Syntax:

The syntax for the “itoa” function is as follows:

char* itoa ( int n, char* s, int base);

In the above statement,

  • “char*” represents the return type of the function.
  • The first parameter “int n” represents the number to be converted...

We are considering the RSA encryption scheme. The involved numbers are small, so the communication is insecure.  Alice's public key (n,public_key) is (247,7). A code breaker manages to factories  247 = 13 x 19  Determine Alice's secret key. To solve the problem, you need not use the extended Euclid algorithm, but you may assume that her private key is one of the following numbers 31,35,55,59,77,89.
Consider the following Turing Machine (TM). Does the TM halt if it begins on the empty tape? If it halts, after how many steps? Does the TM halt if it begins on a tape that contains a single letter A followed by blanks? Justify your answer.
