Did i interprete this C++ problem right?

i want 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%





this is how i code it:





#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 that what the problem is asking me to do? if so, is my code right?

Looks correct to me. As long as your math is right-which it appears to be (seems simple enough). Only thing is this, which has to do with your syntax:





// calculate sum


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


{


total = total + rate[x];


}


//end for





You just forgot the open/close brackets there however perhaps you were coding more of an abstract version of the program.
Reply:use x++ instead of x+1





I think C++ Compiler may consider x+1 in for loop as error.

Reply:the brackets are not necessary for 1 line in a for loop. it's good practice but it is not an error.





x++ is shorter, but otherwise what he is doing "x=x+1" will work fine.
