Question

I have a function that calls a lot of other functions from different objects. Each function has to return true before calling the next one. As you can see I am using too many if statements. How can I improve the code and make it neater? Thanks

bool ISOKToDoSomthing()
{
    boo retVal = false;

    retVal = ObjA.CheckVersion(oldVersion);

    if(retVal)
    {
         retVal = objB.CheckUserRight();
    }

    if(retVal)
    {
          retVal = ObjC.ISDBExist();
    }

    if(retVal)
    {
          retVal = OjbD.ISServerUp(ServerName);
    }
    //tons of similar code as above
    ......... 
    return retVal;
 }

Answer 1

return 
    ObjA.CheckVersion(oldVersion) &&
    objB.CheckUserRight() && 
    ObjC.ISDBExist() && 
    OjbD.ISServerUp(ServerName);
