Here's how things are happening inside if statement. if(a=8||b==5) After considering operator precedence, the statement will become if ( a = ( 8 || ( b == 5) ) ) Which will become if ( a = (8 || 0) ) if ( a = 1 ) And as this is assignment operator, so value of "a" is changed to 1.

Remove one equle (=) from b Then the answer will become 7

You define a = 7, b=1 If (a=8 || b=5 ) Here nighter a =8 nor b=5 So the program will not do this step so it will jump to cout <<" "<<a And a is equal 7 That's all

san sheva S Just edit the code by removing one (=) from b b= 5 Not b==5

san sheva S Here is what happening in code Concept is that (Any value except 0) || (any other expression even with false condition) will return 1 (boolean True) #include<iostream> using namespace std; int main() { int a=7,b=1; //initialisation and assignment if(a=(8||(b==5))) // your code actually like this to compiler , inside if first (8||(b==5) ) evaluated since b not equal to 5 so 0 is return and || operator with 8 will give 1 which then assign to 'a' variable {cout<<a*b<<a<<b;}//output1 here is a*b=1*1=1 a=1 b=1 111 cout<<" "<<a;// here is a=1 so output2 will be value of a which is 1 } Output combination of output1 and output2 which is 111 1
