编程学习网为您整理以下代码实例，主要实现：C++条件编译，希望可以帮到各位朋友。
#include <iostream>
using namespace std;
#define DEBUG
#define MIN(a,b) (((a)<(b)) ? a : b)
int main () {
int i, j;
i = 100;
j = 30;
#ifdef DEBUG
cerr <<"Trace: InsIDe main function" << endl;
#endif
#if 0
/* This is commented part */
cout << MKSTR(HELLO C++) << endl;
#endif
cout <<"The minimum is " << MIN(i, j) << endl;
#ifdef DEBUG
cerr <<"Trace: Coming out of main function" << endl;
#endif
return 0;
}
