Is this a homework problem? What have tried so far and where are you getting stuck?

This counts spaces & punctuation as characters (starting with the 1st character).
string_var = 'The sun is shining. I feel good.';
answer = string_var(1:2:end)
This eliminates periods:
string_var = 'The sun is shining. I feel good.';
string_var(string_var == '.') = '';
answer = string_var(1:2:end)
Change the . to whatever character you want to eliminate. You want a space.
