Hello!

Conceptual note-taking is most useful to show how main ideas and details relate to each other.

Hope I helped? ^ω^

Taking a suitable example in c language explain the of call by value and call by reference concepts.

Degger [83]

Answer: The difference between call by value and call by reference is that in call by value the actual parameters are passed into the function as arguments whereas in call by reference the address of the variables are sent as parameters.

Explanation:

Some examples are:

call by value

#include <stdio.h>

void swap(int, int);

int main()

{ int a = 10, b= 20;

swap(a, b);

printf("a: %d, b: %d\n", a, b);

}

void swap(int c, int d)

{

int t;

t = c; c = d; d = t;

}

OUTPUT

a: 10, b: 20

The value of a and b remain unchanged as the values are local

//call by reference

#include <stdio.h>

void swap(int*, int*);

int main()

{

int a = 10, b = 20;

swap(&a, &b); //passing the address

printf("a: %d, b: %d\n", a, b);

}

void swap(int *c, int *d)

{

int t;

t = *c; *c = *d; *d = t;

}

OUTPUT

a: 20, b: 10

due to dereferencing by the pointer the value can be changed which is call by reference

Which of the following modes of replication requires a very low latency network connection and ensures data remains in synch wit

Snowcat [4.5K]

Answer:

b. Synchronous replication

Explanation:

Replication of data in storage partitions or in a number redundant array of independent disk drives helps to promote redundancy, as implied, and faulty tolerance to reduce loss of data.

There are two categories of replication and they are synchronous and asynchronous replication.

Synchronous replication requires low latency network site to mirror data, while asynchronous replication mirrors data in large metropolitan area in high latency networks.

Professor Midas drives an automobile from Newark to Reno along Interstate 80. His carâ€™s gas tank, when full, holds enough gas

zmey [24]

Answer:

The GREEDY Algorithm

Explanation:

Based on the situation given in question, the Greedy algorithm shall give the optimal solution to professor

Suppose that the cities are at locations0 =x0< x1< . . . < x

We shall use the induction method to prove that G is the optimal solution valid for numbers less than n

We assume another solution Z which we initially consider to be optimum as well, based on that when Z fills the tank, it fills it to full level

Let us state the values in case of n intervals. Given below, we say that g1 is the first stop and z1 is also the first stop.

This can be written as ;

G=g1, g2, . . . , gk

Z=z1, z2, . . . , zk’

Here k’ <= k and k < n

Let I be an idex where for the first time gi is not equal to zi

Considering t= maxi Zi

Z′=g1, z2, z3, . . . , zk′

Now since z2, z3, . . . , zk′ should be an optimal stopping pattern for the problem otherwise we have chosen Z, with smaller gas filling (not feasible)

Using induction hypothesis we conclude thatg2, . . . , gk is an optimal stopping pattern, which is based on greedy algorithm
