Computer Science: A Structured Programming Approach Using C, Third Edition
- C++ PROGRAMProblem Statement:                A 4th grader is having trouble with Permutation and Combination problem in Mathematics, so a friend offered help to create a program they can use. The program contains 3 options, 1st option is for Permutation, 2nd option is Combination and 3rd is for terminating the system. For option 1, Permutation, they uses the following formula: nPr =  ; where r must not be greater than n. It should not proceed if this condition is not met. For 2nd option, Combination, they uses the formula : nCr =  ; where r must not be greater than n as well. For the 3rd option, the program owner’s information shall be displayed, like name, subject code and account number, before the program terminates.  Requirements: Develop the required system and use cpp for the file name Remember that both n and r are variables, their values shall only be entered at run time. The program requires the use of any looping The program requires the use of any conditional Introduce at…arrow_forwardint x; X=-2; do { x++; cout0); cout<<"done"; O done O -2 done O -1 donearrow_forwardThe following statement is incorrect.

E.g., lottery = 123, input = 123(2) If the user input matches the lottery, but in wrong order, print "the award is $6,000". E.g., lottery = 123, input = 321(3) If two digits in the user input matches a digit in the lottery, print "the award is $3,000". E.g., lottery = 123, input = 612(4) If one digit in the user input matches a digit in the lottery, print "the award is $1,000". E.g., lottery = 123, input = 289(5) If none of the digits is matched, print "thank you".arrow_forwardAnalyze the following code: int x = 0;int y = ((x < 100) && (x > 0)) ? 1: -1; The code has syntax error. y becomes 1 after the code is executed. y becomes -1 after the code is executed. The code has run time error.arrow_forward7. Given the following code, what initial values for num will cause an error during execution? int mystery(int num) { if (num 0) == return 0; else if (num 0 B. num > -100 and num < 0 C. num < 0 D. None of these will cause an error. 8. For the code in the previous problem, what will happen if the initial value of num is invalid?arrow_forwardarrow_back_iosSEE MORE QUESTIONSarrow_forward_ios
