To find the most occurring digit

Question

I wanted to make a code that finds the most occurring digit in the long number using a string (and loops). Also, I wanted it to get its input on the user's input. Below is the example:

Input:
34214145

The output should be:
4

I attempted to code, but it's still wrong.

Answer 1

I removed the last two closing curly braces and it showed me the output. the logic is fine so far, its correctly counting.

Answer 2

Let's assume the digit 0 has the maximum frequency.

int max = 0;

Now we check whether that's actually true. Does digit 1 have a higher frequency? If yes we update the max variable.

if (frequency[1] > frequency[max])
max = 1;

Does the number 2 have even higher frequency?

if (frequency[2] > frequency[max])
max = 2;

Now of course all that's left to do is to turn this into a loop :)
