Answer:
C. &&
Explanation:
Of the options provided:
A) ++ : increment operator. For example : ++1 = 2
B) || : Logical OR operator. A || B is true if any one of A or B is true.
C) && : Logical AND operator. A && B is true if both A and B are true.
A B A && B
False False False
False True False
True False False
True True True
D) @ : Ampersand character (commonly used in email addresses) e.g, [email protected]
Answer:
Answered below
Explanation:
//Program is written in Python programming //language.
number_of_trees = int(input ("Enter number of trees purchased: "))
height_of_trees = float(input("Enter height of trees: "))
delivery_status = input("Do you want trees delivered? enter yes or no ")
price_of_two_meters = 20
total_price = number_of_trees * price_of_two_meters
//Invoice
print (number_of_trees)
print(height_of_trees)
print (total_price)
print (delivery_status)
Program p1;
var a,b,c,d : integer; {i presume you give integer numbers for the values of a, b, c }
x1, x2 : real;
begin
write('a='); readln(a);
write('b='); readln(b);
write('c=');readln(c);
d:=b*b - 4*a*c
if a=0 then x1=x2= - c/b
else
if d>0 then begin
x1:=(-b+sqrt(d)) / (2*a);
x2:=(-b - sqrt(d))/(2*a);
end;
else if d=0 then x1=x2= - b /(2*a)
else write ("no specific solution because d<0");
writeln('x1=', x1);
writeln('x2=',x2);
readln;
end.
Answer:
Using python programming language.
Explanation:
#to define the function write as below
def equal():
#to get the two integers from the user
#The user is asked for input in the code below.
x = int(input("Enter the value for X"))
y= int(input("Enter the value for y"))
if x==0 and y==0:
print("both numbers are ", "0")
elif: x==1 and y==1: #This test if both x and y are 1
print("true")
elif: x==y: #this line test if both values are equal
print("true")
else:
print("False")
equal() #end of the function
