Implementation function: enter an integer greater than 1 to n, in the same loop statement
The number of odd and even integers between 1 and n is calculated separately.
* * * * * * * * * * /
# include stdio, h
Void main ()
{int odd, even, I, n.
The scanf ( % d , n);
For (I = 1, odd = 0, even = 0; I = n + I = 2)
{
Odd + = I;
If (I = n + 1)
Even + = I + 1;
}
Printf ( the sum of the odd = % d , odd); / * the sum of odd Numbers * /
Printf ( the sum of even = % d \ n , even); / * the sum of even Numbers * /

[problem 5.030] the system is given an external integer variable n and a long integer variable f
(it doesnt need to be defined by itself). Write the program, n factorial n factorial. And will
The results are stored in f. For example, when n is equal to 6, f is equal to 6. = 1 * 2 *... * 6 = 720.
Note: 0! = 1.
* * * * * * * * * * /
Void main ()
{
Int a = 1;
F = 1;
If (n = = 0) f = 1;
The do
{
F = f * a;
A + = 1;
}
While (a = n);

It needs to be defined by itself. Write the program, n factorial n factorial. ! , and the result
Store it to f. The definition of double factorial is:
When n is odd, n! For the product of all the odd Numbers of n,
Such as: 7!!!!! X 3 x 5 x 7 = 1.
When n is even, the product of all even Numbers that are not greater than n (except for 0),
Such as: 8!!!!! = 2 x 4 x 6 x 8.
