Question

Assume that isIsosceles is a boolean variable, and that the variables isoCount,triangleCount, and polygonCount have all been initialized. Write a statement that adds 1 to each of these count variables (isoCount,triangleCount, and polygonCount)if isIsosceles is true.

Answer 1

To update the count variables isoCount, triangleCount, and polygonCount when isIsosceles is true, an if statement is used in programming that increments each count by 1.

Step-by-step explanation:

In programming, we can use an if statement to test a condition and perform certain operations if the condition is true. In the case of the isIsosceles boolean variable dictating whether isoCount, triangleCount, and polygonCount should be incremented, the code statement would look like this:

if (isIsosceles) {
isoCount++;
triangleCount++;
polygonCount++;
}

This statement checks if isIsosceles is true. If it is, it proceeds to add 1 to each of the count variables, effectively keeping track of how many isosceles triangles we've encountered, which are also triangles and polygons, hence updating the respective counters.
