Question

W.A.P to enter single character print the previous 2 and the next 2 characters .​

Answer 1

Source co‎de: [in Python]

$\tt n\ =\ in put("Enter\ a\ character:\ ")\\print()\\print("The\ previous\ 2\ characters:\ ")\\print(ch r(ord(n)\ -\ 1))\\print(ch r(ord(n)\ -\ 2))\\print()\\print("The\ next\ 2\ characters:\ ")\\print(ch r(ord(n)\ +\ 1))\\print(ch r(ord(n)\ +\ 2))$

Explanation:

Once the character has been entered using the $\tt in put()$ function, we use functions $\tt ch r()$ and $\tt ord()$ to print the previous 2 and next 2 characters corresponding to the character entered. This is in relation to the ASCII values. ASCII values are assigned values/co‎de numbers that represent characters such as letters, numbers, special characters, etc. It helps in the electronic interpretation of what is being typed. An example has been demonstrated below.

$\tt ch r(99)$ would return the character under co‎de 99, which is 'c'. $\tt ord('c')$ would return the co‎de of 'c' which is 99.
