Get started for freeWrite a complete \(\mathrm{C}++\) program that reads in two whole numbers and outputs their sum. Be sure to prompt for input, echo input, and label all output.
Suppose savings and expenses are variables of type double that have been given values. Write an \(i f\) -else statement that outputs the word Solvent, decreases the value of savings by the value of expenses, and sets the value of expenses to \(0,\) provided that savings is at least as large as expenses. If however, savings is less than expenses, the \(i f\) -else statement simply outputs the word Bankrupt, and does not change the value of any variables.
Give an output statement that will produce the following message on the screen: The answer to the question of Life, the Universe, and Everything is 42
Consider a quadratic expression, say \\[ x^{2}-x-2 \\] Describing where this quadratic is positive (that is, greater than 0 ). involves describing a set of numbers that are either less than the smaller root (which is -1 ) or greater than the larger root (which is +2 ). Write a \(\mathrm{C}++\) Boolean expression that is true when this formula has positive values.
The following if-else statement will compile and run without any problems. However, it is not laid out in a way that is consistent with the other if-else statements we have used in our programs. Rewrite it so that the layout (indenting and line breaks) matches the style we used in this chapter. if \((x<\theta)\\{x=7 ; \text { cout }<<\text { "X is now positive." } ;\\}\) else \(\\{x=-7 ; \text { cout }<<\text { "x is now negative."; }\\}\)
