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
Answer: my test says line graph soooo….
Explanation: if its what the test says
Is it asking for a web site like .edu? or something like that?
Answer:
Java solution (because only major programming language that has public static methods)
(import java.io.* before hand)
public static boolean s2f(String fileName, String text){
try{
PrintWriter out = new PrintWriter(new File(fileName));
out.println(text);
out.close();
return true;
}
catch(Exception e){
return false;
}
}
The dual-layer-IP allows ipv4 and ipv6 at the network layer to access a single tcp/udp stack.
<h3>What is the dual IP layer?</h3>
The word dual-stack is a word that connote a full or total duplication of all stages in the protocol stack ranging from its applications to the network layer.
Note that the dual-layer-IP method often gives room for a computer to run IPv4 and IPv6 simultaneously at the network layer, and all of the IP stack can access a different TCP/UDP stack.
