text does not appear on screen

adam2016 (1529)
hi guys,

I'm having a problem with SDL_ttf I am trying to display text to the screen but to no avail,the ttf font is in the same folder as my project and I know it's in the correct folder as the program crashes when it's not so it's not the folder that's an issue,

TTF_init executes fine so as above it's not a problem with it been in a wrong folder,the name is spelled correctly also so I don't know why the text is appearing on the screen I tried searching online but found no clues as to why this is happening

any suggestions?

thanks

(PS this is just the original version,in the revised version I will be applying RAII so that resources are handled in the constructor and destroyed in the destructor)
