Prepare the following strings in advance as an array. Be sure to write everything in full-width characters.
"The difference between being 18 and 81. 18 years old is the one who drowns in love, 81 years old is the one who drowns in the bath. 18 years old is the one who runs down the road, and vice versa.
The person running is 81 years old. An 18-year-old has a fragile heart, and an 81-year-old has a fragile bone. I'm 18 years old and my heart can't stop pounding.
He is 81 years old and can't stop the plane. An 18-year-old can choke on love, and an 81-year-old can choke on rice cakes. I'm concerned about the deviation value
I am 18 years old, and I am 81 years old and concerned about my blood pressure and blood sugar levels. An 18-year-old who doesn't know anything yet, an 81-year-old who doesn't remember anything anymore.
An 18-year-old who is looking for himself, and an 81-year-old who is looking for everyone else. ”- Then have the user enter a search string. Search characters can be up to 10 characters.
・Then, have the user enter a replacement string. Replacement characters can be up to 10 characters. - Perform a prefix match search on the above string and replace all hit strings.
- After replacing, output the result to the screen. If there are no conversion candidates, "Nothing to convert" is displayed.(if the searched string is in more than 1 place on the original string, the replacement will replace all of it)

thanks,I got to the point of searching input and limiting it to 10 characters but I dont know how to replace that searched words.

the debugger let me input my search string and not letting me enter my replacement string. I made it so that 10 letters can be enter into it but it stop working when I put letters over 3. Are there any chance the program is mistaking one japanese word into 3 letters?

Assuming that your Japanese is in Unicode (Hiragana / Katakana) then it'll usually be 2 bytes per character, but it is possible to use three byte Unicode (since the possible range is 21 bits, meaning 3 bytes) What exactly do you mean "not letting me enter my replacement string." I'm pretty sure it didn't try to smack your wrist and tell you off but what exactly did happen? How did you check?

charon it's own is 1 byte - for Unicode you probably need to use the uchar.h header and its' types, but I've never needed them so I can't help you that much.

replacedis a local variable (andsearchAndReplace()is notstatic), this statement does nothing useful. This has nothing to do with your overall issue, though."One man's wage rise is another man's price increase." - Harold Wilson

Try changing the size of
searchStrandreplaceStrto something too large (but still only enter 10 characters). When you make them just large enough and you enter in that many characters,fgets()leaves the\nin the keyboard buffer and the second call tofgets()see it and exits right away."One man's wage rise is another man's price increase." - Harold Wilson
