Thank you all got what I needed...

Question about the expressions below:


cout << 17 / 3.0 << endl;
cout << 12.0 / 6 << endl;

5.66667

I realize about / and integer but why do I get an double result for the first...

Finally back at looking through code...I am trying to eliminate the gotos in the sudoku function below:


I have eliminated simple gotos before...


double sum = 0.0;

int x = 1;
...

You can use % with C# or Java with real values...

Well I have a sudoku solver- in C++ that finds one, many, or no solutions...bad thing is the input I would have to type in by hand...unless I read it in a text file....

CH is correct- trunc is available in C99 standard:

trunc- Truncate to nearest integral value:

double trunc(double x);

returns x rounded to the integer nearest to it but no larger in magnitude

I always thought that if the values are integer and positive the would both return the same value...but that is the only time that is the case...


(int) floor (1.1) = 1
(int)1.1 = 1

If they...

Nope, just pointing out that fact...Allready finished school-good exercise though

Doesn't look like your finished...still need to print the final product result...which you do not seem to have...

A you trying numerical differentiation..if so.

I would test that with some tolerance level:

tolerance a very small number

enter desired tolerance

...
while (tolExceded && something)

Go it to work- used the loop as sugguested...

Trying to eliminate a goto: from Schaums C++ book


double sum = 0.0;

int x = 1;
repeat: sum += 1.0 / x++;

if (x <= N)
goto repeat;

figured out my problem- thanks for all of the insight

Kind of an offshoot of my previous post but this has to do with logarithmic properties

Change of base:

logbX = logaX/logaB

and

logb(X/Y ) = logbX - logbY

Got it bithub...I just what look right from the texts on the matter

Forgot to find the parameter problem..and the caveat about getline...

here is how I would use a string with a struct;


struct exam
{
string name;
};

int main()
{

Sorry got my C/C++ confused- as mention needed to fix


struct a
{
char name[50];
int i;
};

int main(void)

All thought I am brushing back up on C/C++ I would try to solve the problem without using pointers- then make change to pointers


struct a
{
char name[50];
int i;
}

int main(void)

I would try the following- change...


string user_information ( string name1, string name2)
{

cout << "Please give me your first name ";
cin >> name1;
cout << "Please give me your last...

Basically I trying to find an all purpose formula- derived from the following..
