Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer to this question is c)field.
As we know that the feature of an entity is represented by its attribute in the database table. A database table is a set of records of different fields. Each field represents a row in a database table. Each field can contain a set of attributes related to an entity such as a paint color.
So the price of paint will be in its own field. Because there are different colors in the database table. Each color has its own record in form of a field. As you know that each field is a row in the database table. So, each row has the price of a paint color.
Other options are not correct because:
The table contains a list of fields and each field contains its own paint price. The format and file is something different and does not have any relation with the question scenario.
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;
}
Answer:
study-time survey, project schedule, prioritize tasks, reward system.
Explanation:
Time management can be defined as a strategic process which typically involves organizing, planning and controlling the time spent on an activity, so as to effectively and efficiently enhance productivity. Thus, when time is properly managed, it avails us the opportunity to work smartly rather than tediously (hardly) and as such making it possible to achieve quite a lot within a short timeframe. Also, a good time management helps us to deal with work-related pressures and tight schedules through the process of properly allocating the right time to the right activity.
Hence, time-management techniques work most effectively when performed in the following sequential order; study-time survey, project schedule, prioritize tasks, and designing (creating) a reward system.
