    using namespace std;
    
    const int MAX=100;
    int elems[MAX]={1,2,3};
    int card=3;
    
    void Rem(const int e);
    
    void Rem(const int e) {
    	for (int i=0; i<card; i++) {
    		if (elems[i]==e) {
    			for (;i<(card-1); i++) {
    				elems[i]=elems[i+1];
    			}
    			card--;
    		}
    	}
    }
    
    int main() {
    	Rem(2);

    I notice that in main, you did not initialise i.
    C + C++ Compiler: MinGW port of GCC
