 | Re: binary coding [QUOTE=jimJohnson;1212078]I am doing a homework assignment for CSI 330 and not sure how to begin this program. It is asking me to initialize and unsigned int variable mask, with a value whose binary representation has a 1 followed by all 0's. The second part says... For a counter running from … |

| | I don't see the clearing of cin in your code. Here's a full program using Narue's code. Upon failure, you need to clear it and throw away the bad characters. [code] #include <iostream> using namespace std; int main () { int number = 0; // anything but -1. while (number … |

| | A few options for 2-dimensional arrays. [LIST=1] [*]Static allocation. [*]Dynamic allocation. [/LIST] Static allocation is when you know the size of the array beforehand, as you do. You know in advance that the matrix will be a 5 x 5 matrix. So you are in the first category (static). That's … |

| | Without seeing the driver program it's hard to tell, but the design seems flawed. These functions shouldn't take the char[] parameter since they are member functions. Your char[] array is thus passed with the object, so you don't need it as a parameter. Thus I would imagine you would want … |

| | This isn't a code snippet. It's a regular thread. [code] getData(dataFile, data[], count); [/code] Function calls shouldn't have the [] in them. Function prototypes do, but not function calls. Delete the [] in the function call and try recompiling. |
| | Well, I've never heard an American say that Australians say ""You beauty mate", so I won't say you're wrong, I'm just puzzled.

| | In addition, consider the overall design. Do you want to use integers as the values of the sides? I would use doubles. Be wary of comparing doubles using the == operator as you do in [ICODE]isRight ()[/ICODE]. There's a potential for round-off error. Since you are typecasting from integers and …  |
| | Re: Teacher's comp As long as it's a reasonable formula.
