Hi sololearners, im trying to encrypt a sentence with ceaser cypher in c++ but I'm facing problem in this

Question

string str;
getline(cin,str)
For(int i=0;(i<str.length()&&str[i]!='\0');i++)
{
str[i]='a'-str[i]+'z';
cout<<str;
}
this only encryping one string before space.

Answer 1

1) take cout<<str out of the loop.
2) handel the space also

Also looks like you are using a static key = -1 to encipher the text. Generally in Ceaser cypher, we use randomly generated key or ask the key from the user to make the encryptions stronger.
