Thread: Beginner in C + +, small question about a program

Hello,
Currently a student, I started in C + +.
I exercise to create a program to sort 10-digit code here:

Code:

1.	# define N 10
2.	
3.	# include <iostream>
4.	# include <stdlib.h>
5.	using namespace std;
6.	
7.	pos_max int (int t [], int p);
8.	int main ()
9.	(
10.	srand (NULL);
11.	int t [N];
12.	int m;
13.	for (int i = 0; i <N; i + +)
14.	(
15.	
16.	t [i] = rand ()% 9;
17.	court <<t [i] << "";
18.	)
19.	court <<endl;
20.	m = 0
21.	for (; m <N, m + +)
22.	(
23.	court <<m << "" <<N <<endl;
24.	int p = pos_max (t, Nm);
25.	court <<p <<endl;
26.	int to = t [p];
27.	t [p] = t [Nm];
28.	t [Nm] = aux;
29.	)
30.	for (int i = 0; i <N; i + +)
31.	(
32.	court <<t [i] << "";
33.	)
34.	return 0;
35.	)
36.	pos_max int (int * t, int p)
37.	(
38.	int pmax = 0;
39.	for (int i = 0; i <p; i + +)
40.	(
41.	if (t [i]> t [pmax])
42.	(
43.	pmax = i;
44.	)
45.	)
46.	return pmax;47.	)

The problem is that the "m" starts at 10 (see The cost that I placed. Here are the result of a simulation:

6 6 5 7 7 6 1 1 2 4
10 10
0
6 6 5 7 7 6 1 1 2 4.

I do not understand why m not start a 0 and 1 ....

Thank you in advance

Already have your code not compile, missing one, after m = 0

After that t [Nm] that goes beyond the table should be replaced by t [Nm-1] as indexes in your table go from 0 to 9 but otherwise, once it compiles, m good start at 0

I made the change that you told me, but I still have the same problem...

Code:

1.	# define N 10
2.	# include <iostream>
3.	# include <stdlib.h>
4.	using namespace std;
5.	
6.	pos_max int (int t [], int p);
7.	int main ()
8.	(
9.	srand (NULL);
10.	int t [N];
11.	int m;
12.	/ / Making the array.
13.	for (int i = 0; i <N; i + +)
14.	(
15.	
16.	t [i] = rand ()% 9;
17.	court <<t [i] << "";
18.	)
19.	court <<endl;
20.	
21.	
22.	
23.	for (m = 0, m <N, m + +)
24.	(
25.	court <<m << "" <<N <<endl;
26.	int p = pos_max (t, Nm-1);
27.	court <<p <<endl;
28.	int to = t [p];
29.	t [p] = t [Nm-1];
30.	t [Nm-1] = aux;
31.	)
32.	for (int i = 0; i <N; i + +)
33.	(
34.	court <<t [i] << "";
35.	)
36.	return 0;
37.	)
38.	pos_max int (int t, int p)
39.	(
40.	int pmax = 0;
41.	for (int i = 0; i <p; i + +)
42.	(
43.	if (t [i]> t [pmax])
44.	(
45.	pmax = i;
46.	)
47.	)
48.	return pmax;49.	)

I already know how you do it to compile because your function pos_max "takes an int argument instead of int * (for t). After correcting it works.

EDIT: I just saw that you had said the prototype correctly, cons by signing the definition is incorrect

Nan but your call pos_max was well Nm is needed is that after things did not.

Great, it works, I understood! thank you very much.
