Write a simple substitution code for an alphabetic string. That is, declare a permutation of the 26 alphabetic characters i.e. char perm[] = "ajczieaungsdfxmphybklortvw" Now, given a message string e.g. char msg[] = "secret message to encode"; Replace all occurrences of 'a' with 'q' (since perm[0]='q') Replace all occurrences of 'b' with j' (since perm[1]='j'") Replace all occurrences of 'z' with "w' (since perm[25]='w') So that, the message is modified to "bicyik fibbqai km ixcmzi" Improve your solution so that is will handle uppercase characters too, so that if "Secret Message To Encode"; the message is modified to "Bicyik Fibbqai Km Ixcmzi"

Write a simple substitution code for an alphabetic string. That is, declare a
permutation of the 26 alphabetic characters i.e.
char perm[] = "ajczieaungsdfxmphybklortvw"
Now, given a message string e.g.
char msg[] = "secret message to encode";
Replace all occurrences of 'a' with 'q' (since perm[0]='q')
Replace all occurrences of 'b' with 'j' (since perm[1]='j')
Replace all occurrences of 'z' with 'w' (since perm[25]='w')
So that, the message is modified to
"bicyik fibbqai km ixcmzi"
Improve your solution so that is will handle uppercase characters too, so that
if
"Secret Message To Encode";
the message is modified to
"Bicyik Fibbqai Km Ixcmzi"
