C語言沒有字串型別,而是用char array來模擬字串,由於本質是array,所以可以用pointer來表示字串,也因如此,造成C語言在操作字串時含其他語言差異甚大。 1 /* 3 4 Filename : C_string.c 5 Compiler : Visual C++ 8.0 / BCB 6.0 / gcc 3.4.2 / ISO C++ 6 Description : Demo how to use C-Style st...

you want to ensure the actual argument has the `TARGET` attribute also (e.g., object `c` in your main program) and all the subprograms carry through the attribute. This effectivelyrequires you to eschew `FUNCTION` subprograms (e.g., the so-called constructo...
