18 Questions
What is the first step in the computer problem-solving process?
Analyze the problem
What is the purpose of top-down design in computer programming?
To expand every task to the smallest details
What does pseudocode in computer programming use to make the steps in the solution explicit?
A mixture of English and formatting
Which type of operations involve repeating the execution of a block of instructions?
Iterative operations (loops)
What is the formula to compute the perimeter (p) of a triangle with sides a, b, and c?
$p = a + b + c$
What is the correct way to compute the angle (θ) given the coordinates (x,y) of a point?
$θ = tan(y/x)$ if x ≥ 0, else $θ = tan^-1(y/x)$
What does an algorithm consist of?

Solving mathematical problems
In computing, why should a good programmer avoid reinventing the wheel?
Certain problems have already been solved and can be reused
What is the purpose of looking for familiar things in computing, as mentioned in the text?
To reuse existing solutions for similar problems
What is the role of algorithms in computer problem-solving, based on the text?
Providing a set of instructions for solving problems in a finite amount of time
According to the text, what is the first step to understand and solve a problem?
