Why won't this definite while loop work?

[Andrew Charbonneau]

include <stdio.h>

int main()
{ int another = 1;
while(another = 1)
printf("Hello\n")'
printf("Press 1 to recieve another greeting or zero to terminate.\n");
scanf("%f",&another);
}
system("pause");
return(0);

it keeps repeating even if I press 0.!?!?

Thanks!

What is a "definite while loop"?

[Wayne Keen]

%f is to read floats
%i-integer
%d-decimal integer

Note also that

while (another = 1)

Is probably NOT doing what you think it is. = is the assignment
operator, not the comparison operator, which is ==

Your line of code is putting 1 in the variable another, and if it does it successfully, returns true

Consider what this does instead:

while (another == 1)

Don't feel too bad, this is probably my most often done mistake.

Makes me mis Ada, where = is the comparison operator, and := is the assignment operator.
