#include <stdio.h> int main() { int a=8, b=0,c=0; if(!a<10&& !b||c) printf("Rahman"); else printf("abdul"); return 0; } if(!a<10&& !b||c) Is equals to if( ((!a) <10) && (!b) || c) !a = !8 = 0 !b = 1 So if( (0<10) && 1 || 0) Is equals to if( true && 1 || 0) Is equals to True It should print "Rahman"

Abdul Rahman Khan firstly your code has some type and missing parenthesis the correct code should be like this #include <stdio.h> int main() { int a=8, b=0,c=0; if(!(a<10)&& !(b||c)) printf("Rahman"); else printf("abdul"); return 0; } Now how "abdul " is printed? Because 8<10= true which is 1 in boolean the not operation is performed then so 1 become 0 0||0 gives 0 then not operation make it 1 Now 0 && 1 which evaluated as 0 because and(&&) is multiplication and or (||) is sum so it gives 0 and else part is evaluated and printed.

Gordon && has higher precedence than || ! operator has even more higher

true && 1 || 0 Is (true && 1) || 0 Or true && (1||0) ?

That means "a and b or c" is "(a and b) or c", and "a or b and c" is "a or (b and c)"?

true && 1 || 0 is equals to (true && 1) || 0

Thanks for the reference website. I noticed the associativity of Left-to-right, then that explains the above code playground result.
