问题
I have a project and somewhere in my code I'm writing this:
else if (character[0] == '\'){
How can I compare my character with this symbol? Every other symbol that I tried to compare like ,, ;, etc. is done and this is the only symbol that I'm getting a wrong message.
回答1:
The backslash \ is used as an escape character, so you would need to write:
else if (character[0] == '\\'){
In this case the backslash is being used to escape itself.

I'm not clear on what you ask. Do you mean to compare like this:
if (character[0] == '\\') {
or you could do
if (character[0] == 92) { // ASCII-Code
