    Thumbs up using ranged values with the switch flow control statement

    I have a doubt, is there any way to use ranges instead of specific values in a switch statemnt? i.e. how can i do something like:

    Code:
    switch(var){
       case 0 to 100:
         /*Some action*/
         break;
       case 101 to 200:
        /*Something else*/ 
        break;
       default:
         /*Yet something else*/
         break;
    }
    I know it is possible in other languages but I have looked into several C books and online articles and haven't found one that talks about this.

    Many thanks!

    Never seen it done or heard of it either. Just use an If statment.

    in C language you have to use if conditions
    Code:
    if( var >= 0 && var <= 100)
    {
      // do something
    }
    else if( var >= 101 && var <= 200)
    {
      // do something
    }

    You don't have to...
    Code:
    switch( num )
    {
        case  0:case  1:case  2:case  3:case  4:case  5:case  6:case  7:case  8:case  9:
        case 10:case 11:case 12:case 13:case 14:case 15:case 16:case 17:case 18:case 19:
        case 20:case 21:case 22:case 23:case 24:case 25:case 26:case 27:case 28:case 29:
        case 30:case 31:case 32:case 33:case 34:case 35:case 36:case 37:case 38:case 39:
        case 40:case 41:case 42:case 43:case 44:case 45:case 46:case 47:case 48:case 49:
        case 50:case 51:case 52:case 53:case 54:case 55:case 56:case 57:case 58:case 59:
        case 60:case 61:case 62:case 63:case 64:case 65:case 66:case 67:case 68:case 69:
        case 70:case 71:case 72:case 73:case 74:case 75:case 76:case 77:case 78:case 79:
        case 80:case 81:case 82:case 83:case 84:case 85:case 86:case 87:case 88:case 89:
        case 90:case 91:case 92:case 93:case 94:case 95:case 96:case 97:case 98:case 99:
        case 100:
            /* your code here */
        break;
    
        /* The rest is up to you. ;) */
    
    }
