I want to take a string from stdin but I don't want a static array of fixed size

I know that scanf need something where save the stdin input, but I can't do something like this:

char string[10]
scanf("%s",string);

becouse I need to know before how long will be the string in order to allocate the right memory space.

Can you help me to resolve this problem?
