Help with C++ please!!!! this program should show how many students earned a specific score. it is not working

because i type inn 72 and it shows 2 (which is right) but then if i type inn 72, and it shows 4 this time (it keeps increasing by 2 each time. it does the same with any number i type inn. this is my code:


#include %26lt;iostream%26gt;





using std::cout;


using std::cin;


using std::endl;





int main()


{


//declare array


int count = 0;


int searchFor = 0;


int scores[20] = {90, 54, 23, 75, 67, 89, 99, 100, 34, 99,


97, 76, 73, 72, 56, 73, 72, 20, 86, 99};





while (searchFor != -1)


{


// User enters a score


cout %26lt;%26lt; "Enter a score from 0 to 100: " ;


cin %26gt;%26gt; searchFor;





// If score is in the array, then add to count


for (int x = 0; x %26lt; 20; x = x + 1)


{


if (scores[x] == searchFor)


count = count + 1;


//end if


//end for


}


// Display count


cout %26lt;%26lt; "Count: " %26lt;%26lt; count %26lt;%26lt;endl;


}


return 0;


}//end of the searchArray function

You need to reset count each time you start over.


do like so:











while (searchFor != -1)


{


// User enters a score


count = 0;


cout %26lt;%26lt; "Enter a score from 0 to 100: " ;


cin %26gt;%26gt; searchFor;





// If score is in the array, then add to count


for (int x = 0; x %26lt; 20; x = x + 1)


{


if (scores[x] == searchFor)


count = count + 1;


//end if


//end for


}


// Display count


cout %26lt;%26lt; "Count: " %26lt;%26lt; count %26lt;%26lt;endl;


}


return 0;


}
Reply:The problem is because of the scope of the count variable. it is initialized before while loop. So after the while loop ends once, the count variable doesn't de-initialize. Put the declaration of count within the while loop, that way each time the loop begins, the count is re-initialized.
