Answer:
The TAB key
Explanation:
Sam would use the TAB key, located on the left side of the keyboard, to move around his document to add stops and format its information properly.
Pressing the TAB key will introduce a tab code in his document, which is like moving ahead by a certain number of spaces (5,6, 10 spaces for example, depending on the configuration of the document), but without using spaces, using a tab which is a much better option to position, align things up.
I have a very good example of the program you need written on Python. You can use this (sorry for bad tabulation):
import math
import math
def main():
function = input("Enter a function f(x):\n")
x = 0
y = 0
for rows in range(10,-11,-1):
for col in range(-10,11,1):
x=col
roundfx = round(eval(function))
if roundfx == rows:
print("o", end="")
if rows==0 and col==0 and not rows == roundfx:
print("+", end="")
if col == 0 and not rows == 0 and not rows == roundfx:
print("|", end="")
if rows==0 and not col==0 and not rows == roundfx:
print("-", end="")
else:
if not rows == 0:
if not col == 0:
if not rows == roundfx:
print(" ", end="")
print()
main()
Answer:
The trigger code is given below

where (ID1 = Old.ID2 and ID2 = Old.ID1);
end
create trigger F1_Insert
after insert on Friend
for each row
when not exists (select * from Friend
where ID1 = New.ID2 and ID2 = New.ID1)
begin
insert into Friend values (New.ID2, New.ID1);
end
Answer:
Handle the exception in a catch block or throw the exception to the method that called this method.
Explanation:
The try and catch statements occur in pairs. The try statement allows the user to define a block of code to be tested for errors while it is being executed.
The catch statement allows the user to define a block of code to be executed, if an error occurs in the try block.
If an exception is checked by a method, the method either handles the exception in a catch block or throw the exception to the method calling it.
