C/C++ :: How To Read A Line With Spaces

I want to store the address of a customer (with spaces) in a char variable (say cadd). First I tried to use "cin", as we know it reads until it sees any whitespace. So it reads only first word before a white space. So, I used "getline()" function. But when I used it, It didn't wait for the I/P (it skipped it).

char cadd[20];

std::cout<<"Enter Customer Address:
";
std::cin>>cadd;

std::cout<<"Enter Customer Address:
";
std::cin.getline(cadd,20);
