- iii) Find whether the given loop executes infinitely or not? Justify your answer.for(; 2==2; )ALGO(A)x = A[0]p = -1r = nwhile (True) { do { p = p + 1 } while (A[p] < x) do { r = r - 1 } while (A[r] > x) if (p >= r ){ return r } exchange A[p] and A[r]} From the above algorithm, we have to state whether the following statements are True or False(With explanation) (A) At the end of each iteration of the while loop of Line 4, each index of A smaller than p contains an integer smaller than x. (B) At the end of each iteration of the while loop of Line 4, each index of A larger than r contains an integer larger than or equal to x. (C) When ALGO terminates, the integer at index r is x.Please answer all questions for the while loop: while loop x=9; // loop variable while (x>0) { cout << x <<” , “ endl; x = x - 1;// update } Questions: 1.What is the name of loop variable, or loop control variable? 2.How many iterations does the loop do? 3What is initial value of count? 4.What is value of i when the loop exits (fails) 5.What is the output of the code? See below: 9, 8, 7, 6, 5, 4, 3, 2, 1, 6.What is increment in i between each each iteration 7.Observe semicolons, commas 8.When is the variable incremented: Beginning or
- Explain briefly how loop unrolling, re-association, and separate accumulating help in performance optimization. Re-write the following code using 2 x 2 unrolling. void combine(int x[], int n, int *dest){ *dest = 0; for (int i = 0; i < n; i++) { *dest = *dest + x[i]; } }What is the output of the following codes, consider each case independently? What will be the value of x after the following loop is executed? x = 0 For i = 1 To 2 For j = 1 To 3 x = x * i * j Next j Next iC++ Which of the following is a correct way to ensure that once we read a nonnegative value into x, the loop will stop? (1) int x;while(x < 0){cin >> x;if(x < 0)cout << “x must be >=0”;} (2) int x;for(cin >> x ; x < 0 );cin >> x;cout << “x must be >=0”; (3) int x;do{cin >> x;if(x < 0)cout << “x must be >=0”;} (4) int x;cin >> x;while(x < 0){cin >> x;cout << “x must be >=0”;} Choices: a. 2 and 4 b. 3 and 4 c. 2 and 3 d. 1 and 3
- Suppose you can solve a specific problem using for, while or do-while loop. Whichloop can be more suitable in what situation? Describe your opinion with example.This is for r Regarding a for loop, which of the following is not true? The for keyword must be followed by parentheses. Following the for statement, the code to be executed is recognized by it being indented. The number of times the loop will be performed is determined by the length of the vector passed to the for keyword. The for loop can contain other for loops.Do a trace on the for loop below, and show each iteration of the loop in the tracing table until the loop finishes. Each row in the table corresponds to one iteration of the for loop. int j=3, k=2; for(int i = 12; i >7; i--){ k = k + j - - * i ; } The tracing table is here: i i > 7 j k
- For x[5] = {1,2,3,4,5}, a loop is required to output all elements of x? True Falseplease answer all questions about for loop below: for (i = 1; i <= 5; i++) { cout << i << “, ”<<endl; } Questions: What is the name of loop variable, or loop control variable? How many iterations does the loop do? What is initial value of count? What is value of i when the loop exits (fails) What is the output of the code? What is increment in i between each iteration Observe comma in cout When is the variable incremented: Beginning or the end Loop variable must be defined before entering loop This is pretest loop The integer counter, i, controls the number of loop iterationsA criticism of the break statement and the continue statement is that each is unstructured.Actually, break statements and continue statements can always be replaced by structured statements, although doing so can be awkward. Describe in general how you would remove any breakstatement from a loop in a program and replace that statement with some structured equivalent.[Hint: The break statement leaves a loop from within the body of the loop. The other way to leaveis by failing the loop-continuation test. Consider using in the loop-continuation test a second testthat indicates “early exit because of a ‘break’ condition.”] Use the technique you developed here toremove the break statement from the program of Fig. 4.11
