C + + program translation

C + + When it first appeared, C + + programs need to be translated into a C program and compiled by the C compiler to run.

Consider translating the following C + + programs:

class ccar {public:    int price ;     void Setprice (int  p);}; void Ccar::setprice (int  p) {    = p;} int Main () {    ccar car;    Car. Setprice (a);     return 0 ;}

1) c does not have a class data type, it needs to use a struct instead. int price; Translate to a field in the struct, as follows:

struct ccar {    int price ;};

2) member functions in C + + class, Setprice () into C function, need to pass in struct pointer

void Setprice (struct ccar *spint  p) {    sp->price = p;}

3) Translate main function

int Main () {    struct  ccar car;    Setprice (a);         return 0 ;}
