Hi dear cprogramming users and staffs. I m writing a very simple text editor about my homework. I know you dont like homework questions but mine is different.
I wrote find , find-replace , save , about , new , open ... module. But i wasnt succes write a upper-lowercase. I want to all characters to lowercase in any file.
If you help me about tolower() , i think , i can do toupper(). Sorry my bad english. Thank you .
