Find the value of B (true or false) for the following: i= 5; j = 9; B= ! ((i>0) && (i>= j )); (C++)
Using C Language:
Write a program that consists of 2 guessing game.
The first game:
It is a guessing game in which the computer picks a specific number from 1 to 10, then the user guesses the number chosen by the computer and has ten attempts, and in each attempt the chosen number by the computer changes.
The second game:
A guessing game. The computer also chooses a three-digit number, for example: 950 and you have ten attempts to predict the number chosen by the computer.
For example, the user types 390, the computer will tell him that the first digit is wrong, the second digit is correct, but it is not in the correct location, and the last digit, which is 0, is correct.
And the user makes repeated attempts to find the correct whole number
CODE USING C++
Did you know that in lotteries, a 3-digit number with the same numbers in all digits like 777 will hit the jackpot in a casino? In the same manner, let's make a program that will test if a certain 3-digit number hits a jackpot or not by identifying if all the digits of a given number is the same as the second inputted number. If it is, print "Jackpot!"; else, print "Nah".
Let's try this out now!
Input
A line containing two integers separated by a space.
777·7
Output
A line containing a string.
Jackpot!

You can change the arrangement by playing out the accompanying activities: shift the bearing of a section from opening to shutting as well as the other way around without changing the type of the section: for example you can change '(' to ')' and ')' to '('; you can change '[' to ']' and ']' to '['. The activity costs 0 burles. change any square section to adjust section having a similar bearing: for example you can change '[' to '(' however not from '(' to '['; likewise, you can change ']' to ')' yet not from ')' to ']'.
