switch, case etc.

[florenceale]

Hi 

would like to know if with switch function i can use a range instead of a precise value

switch(i)
     {
      case 1:
         res=i;break;
      default:
         res="default";break;
      case 2:
         res=i;break;
      case 3:
         res=i;break;
     }
   Print(res);

like this

switch(i)
     {
      case 1<5:
         res=i;break;
      default:
         res="default";break;
      case 5<10:
         res=i;break;
      case 10<15 :
         res=i;break;
     }
   Print(res);

ora i have to use if

if(0<x<5){



}else if(5<x<10){

}

//etc

Neither this "case 1<5:" (it might always be 1)

nor this "if(0<x<5)" is working in MQL4/5 - just place the cursor above switch and press F1 and start reading..

The documentation page for switch is helpful.

i checked this page before writing here, but it doesnt show the example of a range. 

i know how to do with if, but i wanted to know if i can do also with switch/case

      case 1:
      case 2:
      case 3:
      case 4:
      case 5:
         res=i;break;

True = 1 and false = 0 so you get

if( 3 < 2 < 1 ) if( false < 1 ) if(     0 < 1 ) if(     true  )	if( 3 > 2 > 1 ) if(  true > 1 ) if(     1 > 1 ) if(     false )
