Section 6.2 For...Next Loops

40174:  Given an int variable k that has already been declaredm use a for loop to print a single line consisting of 97 asterisks.  Use no variables other than k.

For k = 1 to 97
Console.Write("*")
Next

40502:  Assume the integer variables counter, low, high, and result have been declared and that low and high have been initialized.  Write a For loop that adds the integers between low and high (inclusive), and stores the result in result.  Your code should not change the values of low and high.  Also, do not declare any additional variables -- use only counter, low, high and result.

result = 0
For counter = low to high
result = result + counter
Next

40176:  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 whole 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.

total = 0
For k = 0 to 50
total = total + k*k
Next

40177:  Given an integer variable n that has been initialized to a positvie value and, in addition, Integer variables k and total that have already been declared, use a For 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.

total = 0
For k = 1 to n
total += k*k*k
Next

40288:  Write a for loop that computes the following sum: 5+10+15+20+...+485+490+495+500.  The sum should be placed in a variable sum that has already been declared and initialized to 0.  In addition, there is another variable, num that has also been declared.  You must not use any other variables.

sum = 0
For num = 5 to 500 step 5
sum += num
Next

40185:  Given an int variable n that has been initialzied to a positive value and, in addition, int variables k and total that have already been declared, use a do...while loop to compute the sum of the cubes of the first n whole numbersx, and store this value in total.  Use no variables other than n, k, and total.

total = 0
For k = 0 to n
total += k*k*k
Next

40385:  Assume the int variables i, lo, hi and result have been declared and that lo and hi have been initialized.  Write a for loop that adds the integers between lo and hi (inclusive), and stores the result in result.  Your code should not change the values of lo and hi.  Also, do not declare any additional variables -- use only i, lo, hi, and result.

result = 0
For i = lo to hi
result += i
Next

40374:  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 should put 1*1 + 2*2 + 3*3 + ... + 49*49 + 50*50 into total.  Use no variables other than k and total.

total = 0
For k = 0 to 50
total = total + k*k
Next

40375:  Given an integer variable n that has been initialized to a positvie value and, in addition, Integer variables k and total that have already been declared, use a For 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.

total = 0
For k = 1 to n
total += k*k*k
Next

40187:  Assume the int variables i, lo, hi and result have been declared and that lo and hi have been initialized.  Assume further tha result has been initialzied to the value 0.  Write a for loop that adds the integers between lo and hi (inclusive), and stores the result in result.  Your code should not change the values of lo and hi.  Also, do not declare any additional variables -- use only i, lo, hi, and result.

For i = lo to hi
result += i
Next

40223:  Give that two Integer variables, total and amount have been declared, write a loop that reads non-negative values into amount and adds them into total.  The loop termiantes when a value less tha 0 is read into amount.  Don't forget to initialize total to 0.  To read a value into amount use a method, getNum() that we provide for you a class named tC:  amount = TC.getNum();

total = 0
amount = 0
Do
total += amount
amount = TC.getNum()
Loop Until (amount < 0)
