int main ()
{
   int a = 5,b = 2;
   printf(\"%d\",a+++++b);

Answer 1

Follow this precesion order

1.++ (pre increment)

2.+ -(addition or subtraction)

3."x"+ "y"add both the sequence

int a = 5,b = 2; printf("%d",a++ + ++b); //a is 5 since it is post increment b is 3 pre increment return 0; //it is 5+3=8
