syntax error in C ++
 

for the following section of code I keep getting these two errors:

syntax error before '}' token

and

confused by earlier errors bailing out

the small section of code is:
do
{
angle = 2*PI*rand()/RAND_MAX;
dx = cos(angle);
dy = sin(angle);
}


The whole code(that i have done):

#include <iostream>

#include <cstdlib>

#include <cmath>

using namespace std;

int main(void)

{
int atHome=0, stepsToTry=5000, home, start;
double x, y, dx, dy, angle;
const int minx = -10;
const int maxx = 10;
const int miny = -10;
const int maxy = 10;
const double PI = 4*atan(1.0);

cout << "Will Waldo make it home? \n\n";

cout << "Input an int to start the random number generator: ";
int myStart;
cin >> myStart;
srand(myStart);

home = (((x>=8) && (x<=10)) && ((y>=8) && (y<=10)));
start = ((x = 0) && (y = 0));

for (stepsToTry = 5000; stepsToTry>0; stepsToTry = stepsToTry - 1)
{
do
{
angle = 2*PI*rand()/RAND_MAX;
dx = cos(angle);
dy = sin(angle);
}
}

return 0;

}

any help at all welcome

What is the 'do' supposed to do ?

In C/C++ there exists only a construct : "do { statments; } while(condition);" , not just do.

It would be enormously helpful if you could:

1. Cut and paste the exact error message

2. Use the [code] tags around your sample code

3. Post back an "ack" to the group when you've solved a problem

Thanx in advance .. PSM

PS:
vladmihaisima is undoubtedly right about the "do" without any "while()" being
the source of your error.

But the exact error - and better formatting - would have helped.

And by all means, please let us know how/if you resolved the problem.

Among other things, that makes *your* question more valuable to *other* LQ folks who might have the *same* question!

I have added a while and fixed that error. I tried to work in to small of increaments. Thanks!
