Can you read multiple lines from stdin?

Question

So i wanted to know if instead of using a char array variable and then the fgets function to read a single line, i could have an array of char pointers (tecnically are strings) and then use fgets?

Answer 1

First, I think that you should have allocated memory for the lines, something like:
char lines[10][10] // 10 lines of 10 chars each, you could also allocate dynamically

Then you can simply read in the lines:
for (int i = 0; i < 10; ++i)
fgets(lines [i], 10, stdin);

This is a very simple code that reads you some lines. You could extend it with some error handling and string processing to suit your needs.

Answer 2

I think that fgets stops reading when it encounters a new line but you could just call it multiple times in a loop and pass it the appropriate pointer each iteration.

Answer 3

I tried this and didn't work:
char *lines[10]; //each position is one line.
// Fill the array.
for (int i = 0; fgets(lines[i], 10, stdin) != NULL; ++i);
