Assume that the int variables i and j have been
declared, and that n has been declared and initialized.
Write code that causes a "triangle" of asterisks of size
n to be output to the screen. Specifically, n lines should
be printed out, the first consisting of a single asterisk,
the second consisting of two asterisks, the third
consistings of three, etc. The last line should consist of
n asterisks. Thus, for example, if n has value 3, the
output of your code should be
*
**
***
You should not output any space characters.
Hint: Use a for loop nested inside another for loop.
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 do...while
loop to compute the sum of the cubes of the first n whole
numbers, and store this value in total . Thus if n equals
4, your code should put 1*1*1 + 2*2*2 + 3*3*3 + 4*4*4 into
total . Use no variables other than n , k , and total .
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 do...while 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 .
Given that two int variables, total and amount, have been
declared, write a loop that reads integers into amount and
adds all the non-negative values into total. The loop
terminates when a value less than 0 is read into amount.
Don't forget to initialize total to 0.
Instructor's notes: This problem requires either a while or
a do-while loop.
Given that two int variables, total and amount , have
been declared, write a sequence of statements that:
initializes total to 0
reads three values into amount , one at a time.
After each value is read in to amount , it is added to the
value in total (that is, total is incremented by the value
in amount ).
Instructor's notes: If you use a loop, it must be a for loop.
And if you use a loop control variable for counting, you
must declare it.
