小白想问一下这个strncpy哪里错了

Question

char a[17]={0};
    char b[17]={0};
    char c[33]={0};
    strncpy(a,"0123456789abcdef",sizeof(a));
    a[sizeof(a)-1] = '\0';
    strncpy(b,"0123456789abcdef",sizeof(b));
    b[sizeof(b)-1] = '\0';
    strcpy(c,a);
    strcat(c,b);
    cout << c<< endl;
    return 0;

vs2012说我错误 1 error C4996: 'strncpy': This function or variable may be unsafe. Consider using strncpy_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details. h:\c++\2.2\2.2\2.2.cpp 13 1 2.2
