Why do i have this output?

[patman]

Hi!

i write the following code and as an output i have "no" "yes".I wonder why i don't have "yes" "yes" instead?What is going on with zero value?

x=0;
if(x=0)
cout<<"yes";
else
cout<<"no";

x=5;
if(x=1)
cout<<"yes";
else
cout<<"no";

Expressions in if statements are evaluated for true-/falsehood; x = 0 evaluates to false. x = 1 evaluates to true. Even if it's an assignment, the result (in x) is still evaluated.

ok thanks chrisname

chris is correct, use the logical operator '==' as follows and both the expression will work as desired

int main ()
{
int x;
x=0;
if(x==0)
cout<<"yes";
else
cout<<"no";

x=5;
if(x==1)
cout<<"yes";
else
cout<<"no";

return 0;
}

You won't get yes yes for that one. (x == 1) will evaluate to false. If, however, you used
if (x)
it would evaluate to true.

ahhh ok, i reread the original post ,,, you are right, the x=5 threw me off, i thought it was supposed to be a 'no' answer,, lol
