Count X

[oldoc63]

This time we are going to count the number of occurrences of a certain letter within a string. Our function will accept a parameter for a string and another for the character which we are going to count. For example, providing the word "mississippi" and the character 's' would result in an answer of 4. These are the steps we are going to take:

1. Define the function to accept two parameters. word for the input string and x for the single character
2. Create a counter to keep track of the occurrences
3. Loop through every letter in the string. If the current letter is equal to the input letter, increase our counter
4. Return the counter after looping through the entire string.

This solution is similar to the last solution. In this case, we are looping through the input string and comparing it against the input character. If they are the same, then we increase the counter.
