这个是pascal语言写的，你看看 var i,j,k,l:longint;p:boolean;begin readln(l);p:=true;if l=2 then begin writeln('T');end else begin for i:=2 to trunc(sqrt(l)) do begin if l mod i=0 then p:=false;end;if p then writeln('T') else writeln('F');end;end.
int main(int argc,char* argv[]){ int n;bool is=true;cout<<"请输入一个整数：";cin>>n;if(n>1){ for(int i=2;i<n;i++){ if(0==n%i){ is=false;break;} } } else { is=false;} if(is){ cout<<"T"<<endl;} else { cout<<"F"<<endl;} system("PAUSE");retu...
