Understanding argv[1] and converting to integer type through Caesar and Substitution project

[admin]

In Caesar project, argv[1] is a string type array that will hold key (integer value) entered by the user. Suppose the user enters 28 as key. Then:

argv[1][0] = 2

argv[1][1] = 8

argv[1][2] = ‘\0’

There was a need to convert string to integer type for argv[1][ ].

In Substitution project, argv[1] is an array of string type that will hold 26 alphabetical characters.

argv[1][0] = first character entered by the user

argv[1][1] = second character entered by the user

…………………………

argv[1][25] = 26th character entered by the user

argv[1][26] = ‘\0’

There might not be a need to convert argv[1][ ] to integer type in case it is decided to replace string characters (entered as plaintext) by matching string characters through index of argv[1][ ].

Just confirming if I am correct?

There is definitely not a need to convert it to an integer, because it is explicitly not an integer. Converting “zyxwvutsrqponmlkjihgfedcba” to an integer doesn’t make any logical sense.

Are you talking about making a new array where you get the numeric ASCII value for each character of the key entered by the user? If so, I don’t think that’s really necessary.[learn_press_profile]
