Answer 1

Line 8: using scanf in C would fail to recognise space separated strings.
Try scanf("%[^\n]%*c", a); instead

Although, simply using scanf works fine if input is a single token

Line 17:
for(int k=strlen(O);k>=0;k--)

k should start with strlen(O) - 1
You may also use (k=t)

Answer 2

you could do it without the second loop and without o[50] by printing each char every time.
there's an extra char since you are iterating with the whole strlen()
should be strlen(a) - 1 ;
and you didn't give yourself enough memory by limiting array size to 50.

Answer 3

Bahha🐧 I did something similar

Answer 4

Infinity and Bahha🐧 thanks guys...
I tried "gets" to check what kind of error I'm getting but in code coach editor there is no errors coming...

Also i tried this snippets infinity, but one test case is not passing..😢

Bahha can you explain fgets fn??

Answer 5

fgets(a, MAX_SIZE, stdin);

a - input variable
MAX_SIZE - upper limit of length
stdin - standard input

Answer 6

Infinity he used gets the first time, then changed it to scanf 😅

Answer 7

ATSHAYA KUMAR.R may be because your array size is not enough try the code I posted.

Answer 8

Try fgets(a,50,stdin);

Answer 9

Bahha🐧 yeah your code passed all test cases.. and Infinity yeah that fgets worked
