is there a way to count repetition without an array?

Question

VERY BASIC COMMANDS

Answer 1

Ipang I was looking at this as well but
int size = 100;
cin.getline(num, size);
or
cin.getline(num[100]);

but doubt that either would work right

Answer 2

athena , i am not very experienced in C++, but why not using something like a dictionary? In python we use this as a counter.

Answer 3

Ipang she stated arrays are not allowed not strings so ...

Answer 4

Without all the restrictions applied, many others had recommended good & viable options BroFar sir.

There are times when assignments got funny requirements, I guess this is just one of them ...

Answer 5

Sounds more like a do while

int i = 0;
int a;
do {
cin >> a;
cout << a << endl;
i++;
}
while (i < 101);

Answer 6

So the values aren't getting saved anywhere, and they're just read in?

That's tricky though.

In that case maybe, to have 21 variables each representing a number's frequency.

Dumb idea, I know : )

Answer 7

athena I made a code that also might demonstrate but at the end I did create an array from the results of the initial result to find the exact numbers

Answer 8

But you are allowed to use array to store the values right athena?

Just you're not allowed to use array as frequency counter?

Answer 9

athena whoa so you have to cin each number then use an exit like 00 so
int num;
int ct;
if (num == 00) { break;} else { ct++;} or something like that
if I understand your question correctly

Answer 10

BroFar kinda thinking about other ways is kinda stupid i guess i shoud declare 21 variable each representing a number between 0-20 then write a for loop for 100 times and each time it should compare it with the other 21 variables sooooo stupid 🤦🏻‍♀️🤦🏻‍♀️

Answer 11

Martin Taylor actually i have to get 100 numbers between 0-20 and i should recognize the most repeated number and count it
the print it as the output

Answer 12

Ipang no even arrays are not allowed just for, while, do while, if

Answer 13

Ipang actually that's as far as i got 😂😂😂

Answer 14

Might work if string was allowed BroFar sir ...

But then, if string was allowed, Bell's recommendation to use char (e.g. in a string) to count frequency would have solved this task straight on.

Answer 15

BroFar actually i am a girl :))
and strings are not allowed either :(

Answer 16

Martin Taylor thank you very much💕💕

Answer 17

bell thanks but i can't use vector

Answer 18

bell it's my homework and our teacher wants us to use loops and conditionals only

and btw i didn't get your code 🙄

Answer 19

Do you have to print only the largest repeated number or print the repetition times of each number. ?
If it is the former then there exists a way

Answer 20

sid the most repeated number with times of repetition
