Thread: Best way to store an input string

I'm extremely rusty at C but is this the best way to store an input string into a char*?

Code:

int length = 100; //initial size

Code:

char * name = malloc(length * sizeof(char)); //allocate mem for 100 chars 
int count = 0; //to keep track of how many chars have been used 
char c; // to store the current char 

while((c = getchar()) != '\n'){ //keep reading until a newline 
    if(count >= length) 
        name = realloc(name, (length += 10) * sizeof(char)); //add room for 10 more chars 
    name[count++] = c 
}

Is this a good way and what could be better?
