How to read and store in memory each line of file using syscalls in C

Question

Im trying to read each line from a file, and store those values in a pointer array. Im new to C so sorry for my scrappy code.

I tried reading char by char, put them in a string, and then "store" that string in the pointer array, since it looked like a simple solution, but im having trouble with memory allocations.

Here is my code:

char *files[100];
char buffer;

int r, i, j;
char temp[100];

int fd=open(argv[1], O_RDONLY);

i=j=0;

 while(read (fd, &buffer, 1) > 0) {
        
        if(buffer != '\n') {
            temp[i] = buffer;
        }
        else{
           
            files[j]=temp;
            j++;
            i=0;

            continue;
            
        }
        i++;

    }

I solved the problem, thanks for the help. I had to allocate memory for each line, otherwise my files vector always pointed to the same buffer. I just added the following line before atributingthe value of temp to files:

files[j] = (char*) malloc (size of (char) * strlen(temp);
