Is this C ++ problem right? can someone please check out!?

first of all i don't quite undurstand the problem and i want to know if it was understood right - this is the problem:





The Federal Reserve wants a program that can give the average interest rate on mortgages using data from four nationally ranked banks. Your tasks are to create a program that calculates the average of values stored in a one-dimensional double array named rates. The program should display the average rate on the screen.


Use the following data to:


Bank of America 6.2%, RBC Centura 7.1%, BB%26amp;T 5.9%, Federal Credit Union 6.0%


code:


#include %26lt;iostream%26gt;





using namespace std;





int main()


{


//declare array


double total = 0;


double average = 0;


double rate[4] = {6.2, 7.1, 5.9, 6.0};








// calculate sum


for (int x = 0; x %26lt; 4; x = x + 1)


total = total + rate[x];


//end for





//calculate and display average


average = total / 4;





cout %26lt;%26lt; "Average: " %26lt;%26lt; average %26lt;%26lt;endl;


return 0;


}//end of the displayAverage program

Is this C ++ problem right? can someone please check out!?
It appears to be correct. I would change x = x+1 in the for loop to x++. To verify compile and run program and output should be "Average: 6.3"
Reply:i have no idea? but i do know you spelled understand wrong in the first sentence. you spelled it undurstand. but thanks for the points
