Hi, sorry I'm opening this post again, is that it is perfect for my doubts. Well Im quite a beginner in programming and Im trying to understand the functions, have doubts about charsmax and sizeof, dont know how to use more actually dont know how to use such as didnt understand a part of this new code "array32 readargv (1, array, charsmax (array))" which means the number 1?. I pray for those who try to help me, I ask you to explain in great detail because I have difficulty in understanding because I dont speak English and use translators to understand, and the translations are bad. Who help me thank you of heart
