printf("\n %d %d",x,y);
after the if statement there is no semicolon sir.If semicolon is there after the if statement what will be the output sir.
If the semicolon is not there, the output will be just values of x and y. If it is, in the other hand, the output will be void. The reason is than the semicolon halts the execution of operators. It just does the if statement, and after that does printf function, independently.
