I want to read input from user using C program. I don't want to use array like,
char names[50];
because if the user gives string of length 10, then the remaining spaces are wasted.
If I use character pointer like,
char *names;
then I need to allocate memory for that in such a way of,
names = (char *)malloc(20 * sizeof(char));
In this case also, there is a possibility of memory wastage.
So, what I need is to dynamically allocate memory for a string which is of exactly same as the length of the string.
Lets assume,
If the user input is "stackoverflow"
, then the memory allocated should be of 14
(i.e. Length of the string = 13 and 1 additional space for '\0').
How could I achieve this?
