Exercise 5

(Please use c++ code)

bool isUnlucky(int all, int len); Implement a function that determines if the unlucky number 13 appears in an array. The function returns true if 13 appears in the array at least once; otherwise it returns false. Write test code that tests every statement in the function. Use assertions in your test code. bool isStrictlylncreasing (int a[], int len); Write a predicate function called isStrictlylncreasing that checks whether an array of integers contains values that are in strictly increasing order. A declaration of the function is shown above. The function returns true if the elements are in strictly increasing order; otherwise it returns false. For example, it will return true for (-2, 4, 5, 6, 8) and it will return false for (3, 4, 6, 6, 9). Write test code that tests every statement in the function. Use assertions in your test code.

Solution

Here are the 2 functions for you:

#include <iostream>
using namespace std;
bool isUnlucky(int a[], int len)
{
for(int i = 0; i < len; i++)
if(a[i] == 13)
return true;
return false;
}
bool isStrictlyIncreasing(int a[], int len)
{
for(int i = 0; i < len-2; i++)
if(a[i] > a[i+1])
return false;
return true;
}
