Thread: Adding array contents

I am doing this array program, and I keep getting an error up when I try to sum the elements of the array

.cpp invalid conversion from `int*' to `int'
.cpp name lookup of `i' changed for new ISO `for' scoping
.cpp using obsolete binding at `i'

Here is the code:

Code:

#include <iostream>	

using std::cout;		
using std::endl;		
using std::cin;			

int main ( void )
{
   int ta = 0;
   int tc = 0;
 		
   int survey1[11] = { 1, 5, 10, 8, 4, 4, 2, 10, 7, 6 };
 		
 		
   char survey2[21] = { 'm', 'f', 'f', 'm', 'f', 'f', 'f', 'm', 'm', 'f',
                        'm', 'f', 'm', 'm', 'm', 'm', 'm', 'f', 'f', 'm' };
		 								 	   
   int survey3[51] = { 1, 2, 1, 2, 2, 2, 1, 1, 1, 1, 
	   	       2, 1, 2, 1, 1, 1, 2, 2, 1, 2,
	   	       1, 2, 1, 1, 1, 2, 2, 2, 2, 2,
	               1, 2, 1, 2, 1, 1, 1, 1, 1, 2,
	  	       1, 2, 1, 2, 1, 2, 1, 1, 2, 2 };
	   										  
   cout << "\tStudent survey result program:\n\n";
		 
   for ( int i = 0; i <= 10; ++i )

  cout << "Survey 1[] = " << survey1[i] << endl;
		 
  ta += survey1;  // ERROR LINE
		 
  cout << "\n\n\n";
					 	   
  for ( int i = 0; i <= 20; ++i )
   
  cout << "Survey 2[] = " << survey2[i] << endl;
     
  cout << "\n\n\n";
     
  for ( int i = 0; i <= 50; ++i )
     
  cout << "Survey 3[] = " << survey3[i] << endl;
     
  cout << "\n\n\n";
     
  cout << "Total of survey 1 is: " << ta << endl
         << "\nTotal of survey 3 is: " << tc << endl;
		 	 
    cin.get();	
    
    return 0;
}

I do not know what the new look up error is, I have never seen
it before.. Anly help appreiciated!

Thanks salem that did the trick! I knew I was on the right track, thanks for the advice, I really shouid of thought of that as I was coding it, maybe I need to slow the pace a little! lol

when you have a for loop containing only one statement, you don't have to have braces, but you should keep it tabbed and right underneath the loop (or next to if short enough) so it is readable.

When you have two or more statments, you keep them in hte braces.

it doesn't hurt to have using for the relevant operations, It's good practice to know the standard library (I'm told), using namespace std kind of eliminates that.
