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. |
|
|
|
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. |
|

|
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. |
total += amount; |
|
|
Given int variables k and total that have already been declared , use a while loop to compute the sum of the squares of the first 50 counting numbers, and store this value in total. Thus your code should put 1*1 + 2*2 + 3*3 +... + 49*49 + 50*50 into total. Use no variables other than k and total. |

|
Given an int variable n that has been initialized to a positive value and, in addition, int variables k and total that have already been declared , use a while loop to compute the sum of the cubes of the first n whole numbers, and store this value in total. Use no variables other than n, k, and total and do not modify the value of n. |

|
Given an int variable n that has already been declared , write some code that repeatedly reads a value inton until at last a number between 1 and 10 (inclusive) has been entered. ASSUME the availability of a variable , stdin, that references a Scanner object associated with standard input. |
|
|
|
Write a loop that reads positive integers from standard input, printing out those values that are greater than 100, each followed by a space, and that terminates when it reads an integer that is not positive. Declare any variables that are needed. ASSUME the availability of a variable , stdin, that references a Scanner object associated with standard input. |

|
|
Write a loop that reads positive integers from standard input, printing out those values that are even, each followed by a space, and that terminates when it reads an integer that is not positive. Declare any variables that are needed. ASSUME the availability of a variable , stdin, that references a Scanner object associated with standard input. |
|
|
|
Write a loop that reads positive integers from standard input and that terminates when it reads an integer that is not positive. After the loop terminates , it prints out, on a line by itself, the sum of all the even integers read. Declare any variables that are needed. ASSUME the availability of a variable , stdin, that references a Scanner object associated with standard input. |

Write a loop that reads positive integers from standard input and that terminates when it reads an integer that is not positive. After the loop terminates , it prints out, separated by a space and on a single line, the sum of all the even integers read and the sum of all the odd integers read. Declare any variables that are needed. ASSUME the availability of a variable , stdin, that references a Scanner object associated with standard input. |
