Which of the following statements about testing are always true. A. If a test fails, there must necessarily be a defect in the executed code. B. If a test passes, there cannot be a defect in any code executed by the test, but there could be a defect elsewhere in the function. C. If a test is unsound, that test passing or failing doesn't tell us whether or not a defect exists. D. All of the above are true

Please tell me where I get wrong.

1. Write function printGrade in void function to compute and output the course grade. The course score is passed as a parameter to the function printGrade. (The program will take 5 inputs for 5 subjects. And show the grade of each subject. And calculate the CGPA) TTTE Percentage Score Quality Point Renark Letter Grade 8e - 100 75 - 79 70- 74 65- 69 6e- 64 55- 59 se - 54 45 - 49 40 - 44 35 - 39 e. 34 Excellent Extrenely Good Very Good Good Fairly Good Satisfactory Quite Satisfactory Poor 4.00 3.67 3.33 3.00 2.67 2.33 2.e0 1.67 1.33 Very Poor Extremely Poor Fail 1.00 Expected Output: Inputs 1.

For each of the 4 functions below, Re-code each one to make it programmer friendly, using standard coding conventions, and documentation. Document each function with: a description of what it does (one sentence) and how it works (no more than 3 sentences). Also, provide a precondition: and a postcondition: statement. (See example for the setTime function below.) 1. 2. setTime(int hours, int minutes, int seconds); //Function to set the time //The time is set according to the parameters //Precondition: All parameters are valid numbers, within the range of clock hours (1-12), minutes (0 - 59), and seconds (0 - 59). //Postcondition: The clockType instance stores the hours, minutes and seconds. // If any of the parameters are not valid the time values will be set to zeros. int _1 (double x) {return (int) (x + 0.5); }; int _2 (char* s) {char*t = s; while (*t!='\0') {t++; }return t-s;}; 3. long 3 (int x,int y) {long n=1; for (int i = 0;i < y;i++) {n*=x; } return n; };

All lines of code in your program can be reached and executed when I run your program  define two functions and they have a "meaningful purpose" to your program. Each function must have more than three statements or lines of code.  At least one function defines a parameter and you use this parameter in a meaningful way  At least one function returns a value back to the code that is calling it and it is used in a meaningful way

Please write the correct code for this question. I really don't know what can be changed.

I am learning c++, and I am really confused about the bool command. Please explain to me how the bool command used and when should I use it! thanks.
