Answer:
<u>Call by reference</u>
In an function if the variables are passed as reference variables this means that the variables are pointing to the original arguments.So the changes made in the function on the reference variables will be reflected back on the original arguments.
For example:-
#include<stdio.h>
void swap(&int f,&int s)
{
int t=f;
f=s;
s =temp;
}
int main()
{
int n,m;
n=45;
m=85;
swap(n,m);
printf("%d %d",m,n);
return 0;
}
the values of m and n will get swapped.
<u>
Call by value</u>
In this program the values of m and n will not get swapped because they are passed by value.So duplicate copies of m and n will be created and manipulation will be done on them.
#include<stdio.h>
void swapv(int f,int s)
{
int t=f;
f=s;
s=temp;
}
int main()
{
int n,m;
n=45;
m=85;
swapv(n,m);
printf("%d %d",n,m);
return 0;
}
Explanation:
The special case that exists in linked list when we are managing them is when we are dealing with the first element of the list.
When we create a linked list we create a first node separately.
If we delete or add element in front of the first element we have to carefully handle that case.
Hence the special case is when we are dealing with the first element of the list.
Answer:
B. a tripod
Explanation:
We cannot have any problem with the electronic viewfinder, because is part of the camera, with this viewfinder we can see the picture that we will take.
A camera lens can be huge or tiny, but we cannot hurt anyone with them, and headphones are harmless.
In this example we have a tripod, there are different types of tripods, but always have three legs, and we could hurt someone if we don't carry it properly.
