char* linker

I have tried to link together three strings(char *), but it didn''t work when I wrote like this: char *path = "path/"; char *name = "file"; char *format = ".dat"; char *adress; adress = path + name + format; // or when I did like this: #define STRING_LINKER(a,b,c) ((a) ## (b) ## (c)) adress = STRING_LINKER(path,name,format); How shall I do it, is there any function that handles this?

char *adress;
adress = (char *)malloc(sizeof(path) + sizeof(name) + sizeof(format));

It should be

adress = (char *)malloc(sizeof(path) + sizeof(name) + sizeof(format)+1);

because C strings need an additional character for 0 termination

It should be strlen instead of sizeof, because the length of strings can not be statically determined outside of their declaration scope (at which point programmatically determining size is always unnecessary).
