I am trying to implement if/if else statements.

for example I want
if(a<b){ statement }
to print something like
"ifbegin a<b" + whatever statement prints + "ifend".

however for
if(a<b){statement1}else{statement2}
it should print
"ifelsebegin a<b" + whatever statement1 prints + " else " + ifelseend

is this possible? I tried the code below but ifelse and if are printed after the statements.

IF '(' expr ')' singlestatement ELSE singlestatement {printf("ifelse")} ;
|
IF '(' expr ')' singlestatement %prec IFX {printf("if")};
