{
    char *a="-100.23";
    float c = 0;
    c=atof(a);
    printf("c:%f\n",c);
    printf("atof(200e-2):%f\n",atof("200e-2"));
    printf("atof(123%^456):%f\n",atof("123%^456"));
    printf("atof(200e-2):%f\n",atof("#$%123%^098"));
    printf("atof( ):%f\n",atof(" "));
    printf("atof(0.02):%f\n",atof("0.02"));
    printf("atof(145):%f\n",atof("145"));
    printf("atof($#@!):%f\n",atof("$#@!"));
    return 0;
