Replace any alphabetic character with '_' in 2-character string passCode. Ex: If passCode is "9a", output is: 9_

oksian1 [2.3K]

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.

Give a recursive (or non-recursive) algorithm to compute the product of two positive integers, m and n, using only addition and

LiRa [457]

Answer:

Multiply(m,n)

1. Initialize product=0.

2. for i=1 to n

3. product = product +m.

4. Output product.

Explanation:

Here we take the variable "product" to store the result m×n. And in this algorithm we find m×n by adding m, n times.

Write a method called fact that recursively calculates the factorial value of its single int parameter. The value returned by fa

andrey2020 [161]

Answer:

The program to this question can be given as follows:

Program:

//class

public class factorial //defining class

{

//method fact

public static long fact(int x1) //defining method fact

{

//conditional statement

if (x1 <= 1) //if block checks parameter value less then equal to 1

{

return 1; //return value

}

else //else part

{

return (fact(x1 - 1) * (long) x1); //return factors using recursive function

}

}

//method main

public static void main(String[] args) //defining main method

{

long data=fact(5);//defining variable that holds function value

System.out.println("Factorial is: "+data); //print value

}

}

Output:

Factorial is: 120

Explanation:

In the above java program, a class is "factorial" is defined, inside the class, a static method "fact" is declared, that accepts an integer parameter that is "x1" and returns a long value, inside this method a conditional statement is used.

If the block it checks parameter value is less then equal to 1, if this condition is true, it will return 1 when this condition is not true. It will go in else part.

In else part, it uses a recursive function to calculate factorial of a number and return its value.
Then the main method is defined, inside this method a long variable "data" is defined, that call and holds fact function return value, and in the next line, the print function is used to print the data variable value.

1. Consider a client and a server connected through one router. Assume the router can start transmitting an incoming packet afte

mezya [45]

Answer:

As the total bytes are L, when h bytes out of L are sent from client to router the router immediately send these h bytes forward to next router. Thus simultaneously another set of h bytes reaches the router and therefore many actions are being performed in a simultaneous way.

Explanation:

For finding end to end delay, calculations are done and briefed.

All the paper work along with explanation is attached for better understanding.
