- What is the value of each of the following Boolean expressions? 54 3=3 2+45 6==7 2+4=6 3+4==4+3 1!=2 2!=2 5==72 3+9=0Use C++ Write a program that simulates flipping a coin to make decisions. The input is how many decisions are needed, and the output is either heads or tails. Assume the input is a value greater than 0. Ex: If the input is: 3 the output is: heads tails heads For reproducibility needed for auto-grading, seed the program with a value of 2. In a real program, you would seed with the current time. In that case, every program's output would be different, which is what is desired but can't be auto-graded. Note: A common student mistake is to call srand() before each call to rand(). But seeding should only be done once, at the start of the program, after which rand() can be called any number of times. Your program must define and call the following function that returns "heads" or "tails".string HeadsOrTails()Because you might want to use a symbolic constant instead of an integer literal in your code.
- Below is a Boolean expression. Write a block of conditional statements (if/elif/else) that will cause the phrase "It works!" to be printed if and only if the Boolean expression evaluates to True. Your code should not use any logical operators (and/or/not), only conditionals and prints (and pass if necessary). You may assume that first, second, third, and fourth are variables which have already been defined as either True or False. (first or not second) and not (third or fourth)What is the difference between the statements continue and break?Q2: Write a program in C++ to read ten students' name and degrees then calculate the average degree for each student if all his degrees above or equal 50. If a student has a degree less than 50, do not calculate the average degree for him. then print the result as shown below: Ahmed Ali Degrees= Math Drawing. 66 66 Ali Assad Degrees= Math Drawing........ 40 50 Name Result Average Ahmed Ali Pass 66 Ali Assad Not pass Note: each student has 7 classes.
- Which of the following statements is/are correct? I. The language L accepts all the strings of a's and b's where the third symbol from left end is b. The regular expression for L is (a + b) b(a + b)*. II. The language L accepts all the strings of a's and b's where the number of a's in a string is divisible by 3. The regular expression for L is (b* ab* ab* ab* )*. III. The regular expression R=(a+b)“ . The number of states required to construct the minimal DFA for the regular expression R is n+2. (A) I and II (B) I and III (C) II and III (D) All are correctWhen giving the user a set of choices to choose from, should numbers be used?E.g. 1, 2, 3? If so, should the choices be treated as integers or strings? What makes the mostsense from the user’s viewpoint? What would make the program easier to debug? Treating choices as integers orstrings?Write in symbolic form:For all integers x,there exists an integer y such that the sum of x and y equals 0.Write in symbolic form:
- Primitive-type local variables are initialized by default. State whether the statement is true or false. If false, explain why.Which of the following statements is/are correct? I. The language L accepts all the strings of a's and b’s where the third symbol from left end is b. The regular expression for L is (a + b)² b(a+b)*. II. The language L accepts all the strings of a's and b's where the number of a's in a string is divisible by 3. The regular expression for L is (b* ab* ab*ab*)* . III. The regular expression R =(a+b)" .
