Find the number of occurrences of a given character in a string

        public static int GetCharacterCount(string input, char c)
        {
            int count = 0;
            
            for (int i = 0; i < input.Length; i++)
            {
                if (input[i] == c)
                {
                    count = count + 1;
                }
            }

            return count;
        }
        

How it works:

For the given character, we loop through the given string character by character and check for equality with the character. If equals we increment a counter and finally return it back.

Enter input: amigo baltigo jijutsu
Enter character: i
Count of i in amigo baltigo jijutsu is = 3
