How to Implement Caesar cipher using programming language C, It should
include the functions for both encryption and decryption. Includes comments to explain
the important steps in the algorithm

please in this part
// check validity of the key
for (int i = 0; i < strlen(argv[1]); i++)
{
if (isdigit(argv[1][i]))
{
valid_key = true;
he gives
[Error] Initial 'for' loop declarations are only allowed in C99 or C11 mode

Thanks a lot for this video, it was really helpful and learned a lot!
Just one thing I didn't really get, why do we have to subtract and add 65 and 97 when we are applying the formula? Could you please point to some more detailed explanation?

[winnieip]

1 more : difference between
Return 0;
Return 1;
When to use which ? Thanks

[winnieip]

1 question : the purpose of
fgets(input, sizeof(input), stdin);
How this differs with get string ? Thanks

How would I incorporate opening an existing file and writing the results to a new file before the offset?

[jdavis]

I don't believe this works properly if the user inputs a negative integer for their key. Any suggestions?

[saaraluthra]

Why is it saying "called object type 'bool' is not a function or function pointer" for me?

[TheXpdf]

This wouldn't work if the key was -100, can someone explain why?

‘Scuse me Mr. Bald friendly Guy, Hey There, can you do some simple, run of the mill, basic of the basic stuff, like what is a { and what program are you using, and btw why do you have that piercing?
