Invalid conversion int to liste in c++

Question

//supression par poition
liste suppos(liste l, int p){
if(p<0)cout<<"position erronee";
else{liste l1=recherchepos(l,p);
if(l1!=NULL) l=suppvaleur(l,l1->x);}
return l;
}

Answer 1

Hmmm...
I have not seen <liste> type, "recherchepos", "suppvaleur" function and "l=" operator in C++ before...
Maybe, "l=" is supposed to be "!=", and others are user-defined class and functions you did not show us (so there is 90% we cannot spot the error).
