False.
The different between break and continue instruction is that with break you exit the loop, and with continue you skip to the next iteration.
So, for example, a loop like
for(i = 1; i <= 10; i++){
if(i <= 5){
print(i);
} else {
break;
}
}
will print 1,2,3,4,5, because when i=6 you will enter the else branch and you will exit the loop because of the break instruction.
On the other hand, a loop like
for(i = 1; i <= 10; i++){
if(i % 2 == 0){
print(i);
} else {
continue;
}
}
Will print 2,4,6,8,10, because if i is even you print it, and if i is odd you will simply skip to the next iteration.
Answer:
Explanation:
Duplicate tuples are not allowed in a relation because the specifications of the constraints of the regional integrity are violated, especially the main constraint that states that there can be no identical values for the attributes of two tuples at any database relation state.
Also, duplicate tuples are not allowed in a relation due to the fact that they lead to redundancy of the data base which in turn, slowing down the speed of the database when data processing such as inserting, querying, updating, deleting, etc are being performed.
I will hope this helps :p
