If

Question

Who can help me?
int a=7,b=1;
if(a=8 || b==5)
cout<<a*b;
cout<<a;

Answer 1

Operator precedence. || (logical or) has a higher precedence than = (assignment).

So the expression if(a=8 || b==5) is the same as if(a = (8 || b==5)). Note that you're using the assignment operator = instead of the comparison operator ==.

The expression (8 || b==5) evalutes to true, or 1 as an integer.

So what if(a=8 || b==5) does is set a to 1 and execute the next line, because the whole expression evalutes to true.

So the output is (1*1=)1.

The last line prints (a=)1 again => output: 11.
