How can I get shell to read special characters as strings? Such as $ or !

How can I get shell to read special characters as strings? Such as $ or !

$ ./ "!hooray!"
bash: !hooray!: event not found
$ ./ !hooray!
bash: !hooray!: event not found
If I escape it, the \ prints in the output:
$ ./ "\!hooray\!"
The code of is as follows:
$ cat
