I am very new to c++ and am currently taking classes to learn the language. I am running into some errors when compiling and am not quite sure why. If anyone has any advice on where I went wrong it would help a ton! I think it is an error with not declaring a variable type. But if I am not mistaking I thought all the variables I used were declared at the very beginning of this function...
Here is the part of what I am trying to compile that is giving errors:
- Code:
double sr(double z);
{
double x = 1;
double right =.5*(x+(z/x));
double diff = abs(right - x);
while (diff > 0.001)
{
x = right;
right = .5*(x+(z/x));
diff = abs(right - x);
}
return x;
}
And the errors I am getting when I compile:
