setlocale in codeblock windows without working right

Question

I have a programming project that was to develop a replica of the naval battle game. however I did all the program on Linux(Ubuntu 16.04) however my teacher uses windows (using codeblocks) and to ensure I went to test the same in windows I had already added to locale.h and the setlocale(LC_ALL, "portuguese") and at first the character ç appeared normal, but the letters a, i... accented whether they are capitalized or not they all go crazy. the Program is divided into several files and some printf are in other files. the setlocale is just at the beginning of main().
