But I still don't quite understand what you're trying to ask. Could we have more info? Read the definition of mode. You can sort the numbers, then find the largest common span, or you can create a histogram, and find the element with the largest count gongzhitaao suggests hash map.
That would be O n time and O n space, slightly better than sorting the array. See here mode — gongzhitaao. Add a comment. Active Oldest Votes.

While it works with the exception of the one typo , it only works when there is a single mode. If there is more than one mode, the output will not reflect that. Anyone viewing this answer should be aware of that and since you are most likely doing this for homework, using this solution will likely be marked incorrect do to invalid output, no matter how valid it may appear.
While convoluted, ali seems to have posted the most accurate way of getting the mode in this post — Turk. Anh Nguyen Anh Nguyen 21 2 2 bronze badges. Aseem Baranwal Aseem Baranwal 3 3 silver badges 10 10 bronze badges.
I know the question is old, but here is a clean and short code that calculates statistical mode: std::sort vector. Harlow44 Harlow44 82 5 5 bronze badges.

I sorted it only because it was one of the requirements for the project. Would you like me to post the whole code insted of just the module? I know what mode is the most re occuring number. Loop through the array get the frequency of each number use the highest frequency to find the mode by storing the numbers of the highest frequency then c out the mode.
Now I may be totally wrong or just partially wrong. I just am trying to figure this out so I can understand this better.
You need special module or function to get array values then find and print mean, median and mode of this array by separate functions. No needs to read array values again and again in every function. About "modular programming". You print array twice before and after sorting with for loops.
Is it a good example of "modularity"? Where is printarray function module? Read the mode term definition again. You have a sorted array and now all you need: count occurencies of every value and return a value corresponded to max counter. That's a code sceleton:. Strictly speaking, this snippet can report the only mode of unimodal arrays or the 1st mode of multimodal arrays. You need the 2nd pass over array to detect all modes. No need to sort an array in that case. For example, see.
I did that just because it made sense to me insted of confusing myself with function calls going everywhich way, We just learned function calls as well with arrays.
He wanted to see that we actually did sort the array so he asked us to print the un sorted numbers then the sorted numbers. Thats why that is there.
