Count the number of letters in English text

Tag: Character uppercase variable indicates English read BSP char = =

Design ideas:

1. First read the text file. Assigns the contents of the resulting text to Str

2. Convert this string to a char array with a For loop at (for Char ch= ' a ';ch< ' z '; ch++) another for loop under this loop. Represents the traversal of an entire array. Defines the count variable. Used to count.

When ch== the letters in the array, Count + 1.

The output ch and the corresponding count will be available.

3. The same means capital letters ' a ' to ' Z '.
