Program that reads the encoded alphabetic text from a file and produces decoded file by replacing each character with the character that occurs five

Posted By: Nicole Hughes     Category: C Programming     Views: 7801

Write a program that reads the encoded alphabetic text
from a file and produces decoded file by replacing each
character with the character that occurs five positions
later in the alphabet A..Z. Character blank should be
replaced with blank itself. Assume that the text consists of only A...Z and blank characters. The replacement should "wrap around" the end of the character set A ..Z so that there is a well-defined replacement for each alphabet.Read text and print its decoded form until a character is found.

Code for Program that reads the encoded alphabetic text from a file and produces decoded file by replacing each character with the character that occurs five in C Programming

#include<stdio.h>
#include<conio.h>

FILE * fin,*fout;
void main()
{
   void input(void);
   void output(void);
   input();
   output();
getch();
}

void input(void)
{
    char c;
    fin=fopen("input12.txt","w");
    printf("\n ENTER THE THE FOR DECODING::");
    while((c=getchar())!=':')
    {
    fprintf(fin,"%c",c);
    }
   fprintf(fin,"%c",c);
   fclose(fin);

}

void output(void)
{
   char c;
   int intc;
   fin=fopen("input12.txt","r");
   fout=fopen("output12.txt","w");
   fprintf(fout,"\n THE DECODED TEXT IS::");
   while((c=getc(fin))!=':')
   {
     // printf("%c",c);if(c!=' ')
      {
     intc=c;
     if(intc+5>122)
     {
        c=96+((intc+5)%122);
     }
     elseif((intc+5>90 && intc+5<96) && intc<97)
     {
        c=64+((intc+5)%90);
     }
     else
       c=intc+5;
      }
       putc(c,fout);
         printf("%c",c);
   }
   fclose(fin);
   fclose(fout);
}
