CSC 110 Assignment 5 (4.1-5.2) Test Questions and Answers Given an integer variable strawsOnCamel, write a statement that uses the auto-increment operator to increase the value of that variable by 1. - AnswersstrawsOnCamel++; Given an integer variable timer, write a statement that uses the auto-decrement operator to decrease the value of that variable by 1. - Answerstimer--; Consider this code: "int v = 20; --v; Sln(v++);". What value is printed, what value is v left with? 20 is printed, v ends up with 19 19 is printed, v ends up with 20 20 is printed, v ends up with 20 19 is printed, v ends up with 19 cannot determine what is printed, v ends up with 20 - Answers19 is printed, v ends up with 20 Consider this code: "int s = 20; int t = s++ + --s;". What are the values of s and t? s is 19 and t is 38 s is 20 and t is 39 s is 19 and t is 39 s is 20 and t is 40 s is 20 and t cannot be determined - Answerss is 20 and t is 40 Given an int variable k that has already been declared, use a while loop to print a single line consisting of 88 asterisks. Use no variables other than k. - Answersk=1; while(k=88) { S('*'); k++; } Sln(); Given an int variable n that has already been declared and initialized to a positive value, use a while loop to print a single line consisting of n asterisks. Use no variables other than n. - Answerswhile(n0){ S("*"); n--; } Given an int variable k that has already been declared, use a do...while loop to print a single line consisting of 53 asterisks. Use no variables other than k. - Answersk=53; do{ S("*"); k--; }while(k=1); Given an int variable n that has already been declared and initialized to a positive value, use a do...while loop to print a single line consisting of n asterisks. Use no variables other than n. - Answersdo{ S("*"); n--; } while(n=1); Given an int variable k that has already been declared, use a for loop to print a single line consisting of 97 asterisks. Use no variables other than k. - Answersfor(k=97;k=1;k--){ S("*"); } Given an int variable n that has already been declared and initialized to a positive value, and another int variable j that has already been declared, use a for loop to print a single line consisting of n asterisks. Thus if n contains 5, five asterisks will be printed. Use no variables other than n and j. - Answersfor (j = 0; j n; j++) { S("*"); } Write a for loop that prints the integers 0 through 39, separated by spaces. - Answersfor(int i = 0; i40; i++) { S(i + " "); } Write a for loop that prints the odd integers 11 through 121 inclusive, separated by spaces. - Answersfor(int i = 11; i=121; i+=2) { S(i + " "); } Write a for loop that prints in ascending order all the positive multiples of 5 that are less than 175, separated by spaces. - Answersfor(int i = 5; i 175; i = i + 5) { S(i + " "); } Write a for loop that prints the integers 50 through 1, separated by spaces. Use no variables other than count. - Answersfor (int count= 50; count = 1; count--) { S(count + " "); } Write a for loop that prints all the even integers from 80 through 20 inclusive, separated by spaces. - Answersfor (int n = 80; n = 20; n-=2) { S(n + " "); } Write a for loop that prints in ascending order all the positive integers less than 200 that are divisible by both 2 and 3, separated by spaces. - Answersfor (int n = 1; n 200; n++) { if (n % 2 == 0) { if (n % 3 == 0) S(n + " "); } } Write a statement that increases the value of the int variable total by the value of the int variable amount. That is, add the value of amount to total and assign the result to total. - Answerstotal += amount; Given int variables k and total that have already been declared, use a for loop to compute the sum of the squares of the first 50 counting numbers, and store this value in total. Thus your code
