- Which of the following statements generates a random integer from 1 to 25 (including 25)? intNum = randGen.Next(1, 25) intNum = randGen.Next(1, 26) intNum = randGen(l, 25) intNum = randGen.NextNumber(1, 26)arrow_forwardThe expression intNum * intNum * intNum is equivalent to which of the following expressions? intNum ^ 3 intNum * 3 intNum ^ 2 * intNum Both a and c.arrow_forwardGiven the following code segment, what will be the value of the variable "num5" after executing the 7th statement? If an error occurs, indicate “error”arrow_forward
- x = 9 ; y = x++ What are the values of x and y after the two statements execute? X = y =arrow_forwardPrint "userNum1 is negative." if userNum1 is less than 0. End with newline. Assign userNum2 with 4 if userNum2 is greater than 9. Otherwise, print "userNum2 is less than or equal to 9.". End with newline. C codearrow_forwardGiven the following code segment, what will be the value of the variable "Val" after executing the third statement? If an error occurs, indicate “error”arrow_forward
- ?Which of the following assignment statements is not correct x = ++x; x++ = y + 2; x += ++y; X = x++ + 2;arrow_forwardAfter the following statements, what are the values of x and y? * x = 15 y = x x = 22 x is 15 and y is 15 x is 22 and y is 22 O x is 15 and y is 22 x is 22 and y is 15arrow_forwardGiven the following code segment, what will be the value of the variable "Val" after executing this statement? If an error occurs, indicate “error”arrow_forward
- Flag question Which of the following statements are valid? Select one or more: {1,2,3,4,5} n {1,4,8, 12} = {1, 2, 3, 4, 5, 8, 12} O {1,3,5,7,9,11,.... } U {2, 4, 6, 8, 10, .... } = N (a, b, c, d, e} n {a, e, i, o, u} = {a, e} Let A = {1, 3, 5, 7, 9}, B = {2, 4, 6, 8} and C = {1,2,3,4}. Then (AUB) = {1,2,3,4} { 1, 3, 5, 7, 9, 11, .……. . For any sets X, Y and Z, the equality (X n Y) u Z = (XU Y) N Z is valid (Hint: You might use venn diagrams to help detemine if the equality is valid) } U {2, 4, 6, 8, 10, . .} = Ø Let A = {1,3,5,7,9}, B = {2, 4, 6, 8} C = {1, 2, 3, 4). Then (An B) UC = {1,2,3,4} If U = {1, 2, 3, ...., 7, 8, 9} then {1,3,5,7,9}º = {2,4,6,8}arrow_forwardGiven the following code segment, what will be the value of the variable "Val" after executing the second statement? If an error occurs, indicate “error”arrow_forwardGiven the following code segment, what will be the value of the variable "Val3" after executing the fourth statement? If an error occurs, indicate “error”arrow_forward
