C++ Exercises: Find all elements in array of integers which have at-least two greater elements
C++ Array: Exercise-6 with Solution
Write a C++ program to find all elements in array of integers which have at-least two greater elements.
Sample Solution:
C++ Code :
#include<iostream>
using namespace std;
void find_greater_elements(int nums[], int n)
{
cout << "\nElements which have at-least two greater elements: ";
for (int i=0; i<n; i++)
{
int ctr = 0;
for (int j=0; j<n; j++)
if (nums[j] > nums[i])
ctr++;
if (ctr >= 2)
cout << nums[i] << " ";
}
}
int main()
{
int nums[] = {7, 12, 9, 15, 19, 32, 56, 70};
int n = sizeof(nums)/sizeof(nums[0]);
cout << "Original array: ";
for (int i=0; i < n; i++)
cout << nums[i] <<" ";
find_greater_elements(nums, n);
return 0;
}
Sample Output:
Original array: 7 12 9 15 19 32 56 70 Elements which have at-least two greater elements: 7 12 9 15 19 32

C++ Programming: Tips of the Day
Can I assume (bool)true == (int)1 for any C++ compiler?
According to the standard, you should be safe with that assumption. The C++ bool type has two values - true and false with corresponding values 1 and 0.
The thing to watch about for is mixing bool expressions and variables with BOOL expression and variables. The latter is defined as FALSE = 0 and TRUE != FALSE, which quite often in practice means that any value different from 0 is considered TRUE.
A lot of modern compilers will actually issue a warning for any code that implicitly tries to cast from BOOL to bool if the BOOL value is different than 0 or 1
