so I want to make 100 random words with 4 length.
Random the ascii first in int then put it in with char.
Ive got alt+f9 successfully. But got an error when ctrl+f9. Is there anything wrong ?
I'm assuming alt-f9 means compile and ctrl-f9 means run. Anyway, in your first for loop, you have the number 1 where you want the letter i.
I should also mention that if you want to use those "words" as c-strings, you'll want to make them one char longer and put a 0 there to null-terminate the string.
