ALGORITHM1. Start2. For each nonterminal A and terminal a do L(A,a):= false;3. For each production of the form A->a or A->B do INSTALL(A,a);4. While STACK not empty repeat step 5& 65.…
LOGIC: To compute FIRST(X) for all grammar symbols x, apply the following rules until no more terminals can be added to any FIRST set.1. if X is terminal, then FIRST(X) is {X}.2.…
LOGIC: Read the input string. By using the FIRST AND FOLLOW values. Verify the FIRST of non terminal and insert the production in the FIRST value If we have any @ terms in FIRST…
ALGORITHMStart.Declare two character arrays str[],token[] and initialize integer variables a=0,b=0,c,d.Input the string from the user.Repeat steps 5 to 12 till str[a] =‟‟.If str[a] =='(‘ or str[a] =='{‘ then token[b] =‟4‟,…
LOGIC: Read the input string. Check whether the string is starting with „/‟ and check next character is „/‟ or‟*‟. If condition satisfies print comment. Else not a comment #include #include…
AIM: Design a lexical analyzer for given language and the lexical analyzer should ignore redundant spaces, tabs and new lines. It should also ignore comments. Although the syntax specification states that…

ALGORITHM:Get the input expression and store it in the input buffer.Read the data from the input buffer one at the time and convert in to corresponding Non Terminal using production…
ALGORITHM:Get the input expression and store it in the input buffer.Read the data from the input buffer one at the time.Using stack and push & pop operation shift and reduce…
