Answer:
The answer is "Option d'.
Explanation:
The database provides a single graphical view of the data, but it provides the facility to use logical view concept, that uses by view command, that uses the dataset to provide a logical view, that shows data according to user condition, and certain options were incorrect which can be described as follows:
- In option a, In logical viewing data, it is not used.
- In option b, It doesn't represent entry screen it simply shows detail.
- In option c, this command doesn't allow you to create duplicate data.
Answer:
It will always return (completely sorted) after 99 data comparisons.
It will always require at least 99 comparisons
Explanation:
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;
}
