[SOLVED]Why this code has no output?

Question

Bennett Post ,HonFu ,~ swim ~ please help 🙏
I was trying to perform reciprocal letter program .
But b4 going for a big program I tried to just copy one string to another...
Actually I don't have to just copy it.. but it's a little part of overall program ....
I have to input an entire line of input so I'm using getline(); function here I don't want to use cin
⚠️Problem is that after copying string when I tried to print it as output it says no output. Please help me to fix it .and also tell me what is wrong with this program so next time I can avoid mistakes
Thank you!

~ swim ~ First of all thank a lot 😊
It works now ...I understand what was problem
And I can use NULL also instead of '\0' but the comparison should be like:
line[i]!=NULL
/*not 'NULL' the ' ' inverted commas shouldn't be used */
Thanks again... It means a lot to me 😊
