Answer:
See explaination
Explanation:
#include<iostream>
#include<map>
using namespace std;
bool contains(int arr[], int size){
map<int,int> nums;
for(int i=0; i< size; i++) nums[arr[i]]=1;
int product;
for(int i=0; i<size-1; i++){
for(int j=i+1;j<size;j++){
product = arr[i]*arr[j];
if (nums[product]==1) return true;
}
}
return false;
}
int main(){
int arr[] ={6,4,-3,-2,0,5};
cout<<boolalpha <<contains(arr,5)<<endl;
return 0;
}

Rectification is "C. The conversation of an AC current to a DC current
Answer:
There is only one modification in the above loop i.e. while loop should be like this--
while (i != n)
{
sum+=arr[i]; // Line 1, In question segment it is line 2.
i++; // Line 2, In question segment it is line 1.
}
Output:
Now if the array input is 1,2,3,4,5 then the output is 15.
Explanation:
In the above question, all the line of the segment is right except the body of the loop because--
- The First line of the loop is increment statement which increments the value of "i" variable from 1 and the value of "i" variable will be 1 in the first iteration of the loop
- The second line starts to add the value from 1'st index position of the array. Hence the segment gives the wrong answer. It adds the arr[1] to arr[n-1].
- So I interchanged both lines of the while loop as shown in the answer part. I make the line 1 (In question segment) as line 2(In answer part) and line 2 (In question segment) as line 1 (In answer part).
Now It gives the correct output because it can add arr[0] to arr[n-1].
