c sscanf分割时间字符串

int main(int argc, char *argv[])
{
   
    char str[]="2006-03-18";
    char str1[10]={0};
    char str2[10]={0};
    char str3[10]={0};
    int a,b,c;
    sscanf(str,"%d-%2d-%2d",&a,&b,&c);
    cout<<a<<" "<<b<<" "<<c<<endl;
    sprintf(str,"%d%02d%02d",a,b,c);
    cout<<str<<endl;
    return 0;
