Ultraviolet A 458-the decoder

The decoder

Write a complete program that will correctly decode a set of characters into a valid message. your program shocould read a given file of a simple coded set of characters and print the exact message that the characters contain. the code key for this simple coding is a one for one character substitution based uponSingle arithmetic manipulationOf the printable portion of the ASCII character set.

 

Input and Output

For example: with the input file that contains:

 

1JKJ‘pz‘{ol‘{yhklthyr‘vm‘{ol‘Jvu{yvs‘Kh{h‘Jvywvyh{pvu51PIT‘pz‘h‘{yhklthyr‘vm‘{ol‘Pu{lyuh{pvuhs‘I|zpulzz‘Thjopul‘Jvywvyh{pvu51KLJ‘pz‘{ol‘{yhklthyr‘vm‘{ol‘Kpnp{hs‘Lx|pwtlu{‘Jvywvyh{pvu5

Your program shocould print the message:

*CDC is the trademark of the Control Data Corporation.*IBM is a trademark of the International Business Machine Corporation.*DEC is the trademark of the Digital Equipment Corporation.

Your program shocould accept all sets of characters that use the same encoding scheme and shocould print the actual message of each set of characters.

 

Sample Input

 

1JKJ‘pz‘{ol‘{yhklthyr‘vm‘{ol‘Jvu{yvs‘Kh{h‘Jvywvyh{pvu51PIT‘pz‘h‘{yhklthyr‘vm‘{ol‘Pu{lyuh{pvuhs‘I|zpulzz‘Thjopul‘Jvywvyh{pvu51KLJ‘pz‘{ol‘{yhklthyr‘vm‘{ol‘Kpnp{hs‘Lx|pwtlu{‘Jvywvyh{pvu5

 

Sample output

 

*CDC is the trademark of the Control Data Corporation.*IBM is a trademark of the International Business Machine Corporation.*DEC is the trademark of the Digital Equipment Corporation.

1 // the sample has already been told. Reduce the output by 7 to 2 // because space needs to be read, it is not recommended to use CIN >>, and it should be changed to getchar (); 3 // the following code: 4 # include <iostream> 5 # include <string. h> 6 # include <stdio. h> 7 # include <ctype. h> 8 # include <algorithm> 9 # include <stack> 10 # include <queue> 11 # include <set> 12 # include <math. h> 13 # include <vector> 14 # include <map> 15 # include <deque> 16 # include <list> 17 using namespace STD; 18 int main () 19 {20 char ch; 21 While (~ (CH = getchar () 22 putchar (CH = '\ n '?
