I used files for this task, and everything works perfectly.

I finally managed to find an answer to this question myself:
#include <cstdio>
#include <vector>

using namespace std;

int main()
{
FILE *f = fopen("input.txt", "r");
char a;
vector <char> v;
while (f != NULL && fscanf(f, "%c", &a) != EOF)
v.push_back(a);
fclose(f);
//
f = fopen("output.txt", "w");
fprintf(f, "%u", v.size());
return 0;
}

For example:
User inputs:
Hello, //enter
world!.
My program has to output 13.
But I`ve no idea, how should I make it stop waiting for input after '!'.

My problem - is to input text - some strings. There can be any text given (look at the example) - some sentences, article from newspaper, short tale, etc. But the problem is that there are '\n' symbols at the end of each string, and I have absolutely no idea how to input all that thing in one string - neither cin nor scanf inputs it. In my code I think problem is in endless while operator, but I don`t have to know how to change that.
I know strlen function, that`s not the problem.

I DON`T HAVE VALUES ENOUGH TO COMPLETE MY ALGORITHM!!! ON VALUES GIVEN TO ME IT WORKS PERFECT!!! don`t be nut!

Member 13527256 26-Nov-17 12:59pm View

Then I might didn`t understand you correct. ALL elements mustn`t be divided by 7; all EVEN numbers mustn`t be divided by 3 moreover. So there might be uneven numbers, and they mustn`t be divided by 7.

Member 13527256 26-Nov-17 7:15am View

Yes: but NOT divided by 7.
So:
(1) each item must NOT be exactly divided by 7
(2) each item must be exactly divided by 2
(3) each item must NOT be exactly divided by 3

Member 13527256 26-Nov-17 3:20am View

Well, there can be any numbers you`d like: 87 3 36 63 78 68 44. They don`t have to be consecutive.

The debugger won`t help me to deal with problems in my algorithm - and all my problems are in that. I tried many times, and I can`t see them. And that`s why I am asking other people to help me.
I`m not a beginner actually, and I know how to use debugger. On values given to me everything works perfectly.

Yes, that IS my problem - to find mistakes in my algorithm. I tried many times, but I can`t see them, and that`s why I am writing to this website.

Member 13527256 26-Nov-17 2:29am View

You input the size of array. Then you input numbers - elements of that array. Among those elements you have to find the longest succession of numbers, not divided by 7 and even numbers, not divided by 3. You have to output the length of this succession.

it`s OK, the numbers divided by 7 don`t have to be even.

Member 13527256 25-Nov-17 9:53am View

Debugger does not help you to find errors with answer in that case, when particular value is not given, and you have to think of billion causes. Here is that situation. I don`t have list of values; and believe me: I have tried to get over this problem for about two weeks when I finally found this website.

Member 13527256 25-Nov-17 9:43am View

I have tested many values, and on each one everything works CORRECT. Maybe, there are some another values, which doesn`t work with this code, but I can`t find them.

Member 13527256 25-Nov-17 8:08am View

THANK YOU VERY MUCH! After a billion of my tries to change it, the answer was that easy!

Member 13527256 25-Nov-17 5:17am View

Well, I said that I`ve tested my program on many different values, and it worked. I`ve no idea on which value it does not work (crushes - was a mistake) as well as I`ve no idea why it actually doesn`t work.
I used to work in different group, where they started using cout/cin, new/delete because their tutor considers malloc/calloc and printf/scanf to be too old and inconvenient.
Actually, in previous group (about a year ago) I used to work with classes and even won a regional programing competition. But then I had to move to another city and my new tutor is not as good as my previous one (moreover, my current group has just started learning to code, so neither they nor tutor like me). Now I don`t usually have problems with coding (last week we had even more complicated task, which I did very fast), but this task I don`t really understand. I think this code should be correct and I can`t understand why it doesn`t work.

Member 13527256 25-Nov-17 4:39am View

If you "know C++" then you know C - it's a subset of C++.
I now that, I mean that they use malloc(), calloc(), printf(), scanf() and etc., which I don`t know.
I just wanted other people to look through my code - for them it woutld be easier to find a mistake.

Member 13527256 18-Nov-17 7:20am View

Thank you - I was working late at night yesterday and forgot about debugger) Actually, the problem was here:
for (auto i:v)
if (max <= i)
{
max = i;
ind = i;
}
ind should be increased by 1 on each iteration here.
