C++ Loops

C++ Loops

(OP)
Can anyone give advice/help with a minor programming glitch.We are trying to write a small program for a BTEC college project and are experiencing difficulty making the FOR LOOP operate correctly. If we enter the number of wall we wish to find the area of it always returns one less than the actual number asked for and will not total the overall area.
Can you suggest a loop which will calculate the area of a user specified amount of walls and return the total wall area. Any loop will do.

Your assistance with this is much appreciated,

Thank you

RE: C++ Loops

Its very difficult to see any problems with the code without viewing the code, as the problem may not be in the loop, please supply more info.

RE: C++ Loops

Hopefully you have solved this by now - 3 months or so on

anyway, try starting your loop at zero:

// This should compile on even the most ancient C++ compiler.

#include <iostream.h>
int main(int argc, char * argv[])
{
double width   = 3.5;
double height  = 2.6;
double total   = 0;
int    NumWals = 4;

// loop from 0 to < NumWalls gives "NumWalls" iterations.
// you could also loop from 1 to <= NumWalls for same result
int wall = 0;
for (wall=0; wall<NumWalls;wall++)
{
  total = total + (width * height);
}

cout << "Total Area is " << total << endl;
}

Hey - I was bored ok!
