Assign value to element of dynamic array

Question

I have two arrays:

char line[128] which is populated using:

fgets(line,sizeof line, file)

and

char* array;
  array=(char*) malloc(j*sizeof(char));

where j is some integer.

I'd like to assign an element of "line" to the corresponding element of "array".

Thanks in advance for any help!

As these are char arrays you could just use strcpy

 strcpy(array,line);

taking care that your dynamic array is large enough to accomodate the line array. This would copy the whole array, or for just an individual element,

 array[i] = line[i];

taking care that i is within limits of the arrays.

 array[N] = line[N]; // N is the corresponding element's index

But you have to make sure that N is a valid index w.r.t both array and line.
