C函数和C++函数相互调用

test.c

int call_MyMath_sum (int,int); int sum(inta , intb) { return call_MyMath_sum(a,b);}

main.cpp

#include <iostream> using namespace std; extern"C" { int sum(int, int); } class MyMath { public:     static int sum(int, int); }; intMyMath::sum(inta, intb) {     return(a + b); } extern"C" int call_MyMath_sum (inta , intb) {    return(MyMath::sum(a,b)); } int main(void) {    cout<<sum(5,6);    return0; }
