can anyone perform a code that when a user asked to put an email adress, the program prints output when find '@'( in c lang...)

Answer 1

No idea what language you want, but just split the string by “@“ and take the first part. In JS:

var str = “[e-mail]”
var email = str.split(“@“)[0]

Answer 2

in java
String email = "[e-mail]";
if(email.contains("@") && email.contains("."))
{System.out.println(email);
}

else System.out.println("Your email is invalid");
