Answer 2

You can change your code to this:

for(int k=19;k>=0;k--){
out[19-k]=in[k];
}
for (int l=0; l<20; l++)
cout << out[l];

You can't use same index "i" for every loop cause it keeps changing.

Answer 3

Good luck, I am not that into C++, I usually code in Java, so my syntaxes might be different than yours.

Answer 4

But we need to store the word in 'out' from 'in' ...so we need same var...isn't it

Answer 5

Yes, I stored it, in out[19-k]=in[k]

If you want words, then char can't store words you need to use string.

Answer 6

Its a char array..
it can store a word I think...
I hv introduced third array temp n did it like swapping but didn't got the output

Answer 7

Okay, give me a sample, what you want to input, and what you expect the output to be.

Answer 8

Just rev the input:
Blue
eulB

Answer 9

Yes thats a string. Char can hold only one letter.

In sololearn playground you have to enter it like this:
B
l
u
e
Split it in line.

Answer 10

Ok..then I will try to use strcpy n getline functions

Answer 11

If its working.. then good.. I haven't checked yet.. though it seems correct.. and you didn't use getline or strcpy

Answer 12

I tried getline n strcpy bt it didn't ..
So I used simply 'cin' instead

Answer 13

Okay, good
