Count number of occurrences of a digit within a string

Question

So I\'m trying to count the number of occurrences of each digit within an array.

My code I\'ve got so far looks like the following:

#include 

        

Answer 1

Consider this modified code:

#include 
#include 

int main()
{
  int numbers [10]= {1, 4, 5, 5, 5, 6, 6, 3, 2, 1};
  int count = 0;

  for(int i = 0; i < 10; i++) { //i = current digit
    for (int j = 0; j < 10; j++) { //j = index in array
      if (i == numbers[j]) {
        count++;
      }
    }
    printf("Number %d has occured %d times \n", i, count);
    count = 0;
  }
}

Output:

Number 0 has occured 0 times 
Number 1 has occured 2 times 
Number 2 has occured 1 times 
Number 3 has occured 1 times 
Number 4 has occured 1 times 
Number 5 has occured 3 times 
Number 6 has occured 2 times 
Number 7 has occured 0 times 
Number 8 has occured 0 times 
Number 9 has occured 0 times 

You were counting how often each digit occuring in the array (including duplicate digits in the array) occured.
