Question

Explain why the following if statement results in syntax error in C, Java, and C#?

   if (x==1) y = 2 else y = 3;

Answer 1

Answer :

The correct statement of ' if ' statement is :

                       if(condition) {
                      // Statements inside body of if
                            }
                       else {
                     //Statements inside body of else
                            }

This is the only valid syntax in which ' if ' statement is written otherwise it will result in syntax error ( for the above question compiler will treat the whole 'if statement' in continuation as 'condition' which will further show syntax error)  .

for the above question, the correct syntax will be:

if (x==1)

y=2 ;

else

y=3 ;
