In order to determine whether the character you entered is a letter of the alphabet, you should use this function: C. isalpha ().
A function can be defined as a named portion of a block of executable code that is written to perform a specific task, which is usually a single, related action.
This ultimately implies that, a function comprises a group of related statements (executable blocks of code) that would only run and return a data whenever it is called by a software program.
In Computer programming, you should use the isalpha () function to determine whether the character you entered is a letter of the alphabet because it would return a true (a non-zero number), if the argument is a letter of the alphabet.
