is there a way to count repetition without an array?

VERY BASIC COMMANDS

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

athena , i am not very experienced in C++, but why not using something like a dictionary? In python we use this as a counter. https://www.techiedelight.com/increment-map-value-associated-with-key-cpp/

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

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 ...

Sounds more like a do while int i = 0; int a; do { cin >> a; cout << a << endl; i++; } while (i < 101); https://code.sololearn.com/c3yORki033ec/?ref=app

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 : )

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 https://code.sololearn.com/cYclByYbE2NS/?ref=app

But you are allowed to use array to store the values right athena? Just you're not allowed to use array as frequency counter?

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

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 🤦🏻‍♀️🤦🏻‍♀️

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

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

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.

bell it's my homework and our teacher wants us to use loops and conditionals only and btw i didn't get your code 🙄

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

sid the most repeated number with times of repetition
