Answer:
Constraint is defined as a part of individual attribute or column. In terms of computer programming, constraints relation are stated in the form of variable. Basically, constraint is the rule that are use for optimization purpose.
There are different types of constraints that are:
- Primary key constraint : It is defined as, the combination of columns which uniquely identify each data in the database table.
- Unique constraint : Unique constraint are used to ensure that all the values in the column table in the database are must be different.
- Not null constraint : It basically prevent all the null values from entering into one or more than one column in a table.

Answer:
function
increase_elements_by_x (list, x)
{
var tplist = [];
for (i = 0; i < list.length; i++)
{
tplist[i] = list[i] + x;
print (tplist[i])}
return tplist;
}
var list =[1, 3, 5];
var copyList;
var x = 3;
copyList = increase_elements_by_x (list, x);
print (copyList);
Explanation:
Create a list named list with initial data 1,3,5.
Create a function name increase_elements_by_x which takes list and number as argument.Create empty list tplist. Loop through list, for ever index add x to list[index] and save to an empty list tplist. After loop is exited return tplist.
create a variable copylist and set it to increase_elements_by_x. Value returned by increase_elements_by_x will be saved in copylist. print copy list to see content of copy list.
Answer:
Explanation:
There are two reasons, first, the operating system could be blocked because a program with poorly written user program does not allow for enough stack space.
Second, the kernel can leave data in the user memory of a program, and this data can be used for another user to get another delicate information.
This is not a computers and technology question but ill still answer it and the answer to this that i think it is ...A ...but i may be wrong
