START
Step 1 Declare array of string, ch, i, freq to 0, vow to 0, word to 0
Step 2 Input a string and a character ch
Step 3 Loop for from i to 0 and str[i]!=’\o’ and ++i
Step 3.1 IF statement for ch==str[i]
   Post incrementing freq
   Step 3.2 End If
   Step 3.3 IF statement
   str[i]=='a'||str[i]=='e'||str[i]=='i'||str[i]=='o'||str[i]=='u'||str[i]=='A'||str[i]=='E'||str[i]=='I'||str[i]=='O'||str[i]=='U'
      Post incrementing vow
   Step 3.4 End If
   Step 3.5 IF statement str[i]=’ ’
      Post incrementing word
   Step 3.6 End If
Step 4 End For loop
