*I have some input about propositional calculus
*After calculating some math funtion-removing paranthesis-changing"&" with 
   ","-replacing "|" with","


I have >>
  (1)  P,-Q,Q,-R is stored in mainp[0] 
       R,A,P,B,F   is stored in mainp[1]


*My question is:
  Between comma , I have want to compare two pointer array. 
    If there is any equal two or more functions(Q,-R is function representation) 
        ,function which you will show me how to write  must return int.
  According to example (1),function will return 1 (I expect like that)

/*I have som thought://which function should I have use:*/
     in for loop
    if( strspn(mainp[0][i])==1 )
        increment d;
        continue;
    or
    in for loop 
      srtcmp(mainp[0][i],mainp[1]);
