Every "while" loop can be re-written using a "for" loop. O True O False

The body of a while loop can consist of ____________. a. a single statement b. a block of statements within curly braces c. either a or b d. neither a nor b

The program in the Programming Example: Fibonacci Number does not check whether the first number entered by the user is less than or equal to the second number and whether both the numbers are non-negative. Also, the program does not check whether the user entered a valid value for the position of the desired number in the Fibonacci sequence. Rewrite that program so that it checks for these things.

A structure that allows repeated execution of a block of statements is a(n) _____________. sequence selection array loop

(Electrical eng.) a. An electrical manufacturer tests five generators by measuring their output voltages at three different times. Write a C++ program that uses a nested loop to enter each generator’s test results, and then computes and displays the average voltage for each generator. Assume the following generator test results: 1stgenerator:122.5122.7123.02ndgenerator:120.2127.0125.13rdgenerator:121.7124.9126.04thgenerator:122.9123.8126.75thgenerator:121.5124.7122.6 b. Modify the program written for Exercise 3a to calculate and display the average voltage for all the generators. (Hint: Use a second variable to store the total of all the generator’s voltages.)

(Misc. application) a. Write a program to reverse the digits of a positive integer number. For example, if the number 8735 is entered, the number displayed should be 5378. (Hint: Use a do statement and continuously strip off and display the number’s units digit. If the variable numinitially contains the number entered, the units digit is obtained as (num % 10). After a units digit is displayed, dividing the number by 10 sets up the number for the next iteration. Therefore, (873510)is5and(8735/10)is873. The do statement should continue as long as the remaining number is not 0.) b. Run the program written in Exercise 3a and verify the program by using appropriate test data.

(Misc. application) a. Write a program that continuously requests a grade to be entered. If the grade is less than 0 or greater than 100, your program should print an appropriate message informing the user that an invalid grade has been entered; else, the grade should be added to a total. When a grade of 999 is entered, the program should exit the repetition loop and compute and display the average of the valid grades entered. b. Run the program written in Exercise 2a and verify the program by using appropriate test data.

What is the output of the following code segment?inta=3,b=4;if(a==b);Write(X);Write(Y); X Y XY nothing

The following program has syntax errors. Correct them. On each successive line, assume that any preceding error has been corrected. (12) const char = STAR = '*' const int PRIME = 71; int main { int count, sum; double x; count = 1; sum = count + PRIME; x = 25.67 newNum = count * ONE + 2; sum + count = sum; (x + sum) ++; x = x + sum * COUNT; sum += 3 ; cout " count = " count ", sum = " sum ", PRIME = " Prime endl; }

(Mathematical functions) Write a program that calculates and displays values for y when y=xz/(xz) Your program should calculate y for values of x ranging between 1 and 5 and values of z ranging between 2 and 6. The x variable should control the outer loop and be incremented in steps of 1, and z should be incremented in steps of 1. Your program should also display the message Function Undefined when the x and z values are equal.
