1. yeah, but why does that mean more power?

2. you could replace the whole switch with a small array (no more conditionals):
Code:
```  int total[]={0/*unused*/,25,55,45,...};
printf(...)
scanf("%u",&order);
sum+=total[order%the_appropriate_value];```

Although it probably is a good idea to range-check the values.

4. You CAN of course use if/else instead of switch/case - but consider what the compiler does if you have a value 8 for this:
Code:
```if(order==1){
total=25.00;
}
else if (order==2){
total=55.00;
}
else if(order==3){
total=45.00;
}
else if (order==4){
total=35.00;
}
else if(order==5){
total=50.00;
}
else if (order==6){
total=70.00;
}
else if(order==7){
total=80.00;
}
else if(order==8){
total=15.00;
}```
Unless it figures out that it's a "switch in disguise", it will compare down the chain until it finds the one that matches. In a switch/case block, the compiler will (most of the time) generate a jump-table, which means that no matter how many variants it is, there will be a O(1) type, rather than O(n) that the if/else version does.

Note that reasonably modern/clever compilers, such as gcc 3.4 can not figure out that the above is a "switch/case in disguise". I just tried out the above code as a if/else, and as a switch/case, and for the average case, the code is simply shorter and better for the switch/case statement.

But if it's part of your assignment to use if-else, then do so.
