Question

•• E3.5Write a program that reads three numbers and prints “increasing” if they are in increasing order, “decreasing” if they are in decreasing order, and “neither” otherwise. Here, “increasing” means “strictly increasing”, with each value larger than its predecessor. The sequence 3 4 4 would not be considered increasing.

•• E3.6Repeat Exercise •• E3.5, but before reading the numbers, ask the user whether increasing/decreasing should be “strict” or “lenient”. In lenient mode, the sequence 3 4 4 is increasing and the sequence 4 4 4 is both increasing and decreasing.

Answer 1

Since you have not mentioned the language of your preference, I am providing the code in C++.

E3.5

CODE

#include <iostream>

using namespace std;

int main() {

int a, b, c;

cout << "Enter three numbers: ";

cin >> a >> b >> c;

if (a < b < c) {

cout << "increasing";

} else if (a > b > c) {

cout << "decreasing";

} else {

cout << "neither";

}

}
