Compiling Problems...

I tried making a simple file encrypter....

what it does it open a file, get 1 char by char. take that char and add the "key" to it..

So char "A" which is 65 added to (lets say key is 1) 1 is 66 which is "B"

the dycrpted would decrypt this but i cant compile it. And please check for errors or any suggestions, and if this program will work

These are teh compile errors under cl.exe

Code:

---

xcrypt.cpp
xcrypt.cpp(37) : error C2362: initialization of 'make' is skipped by 'goto end'
        xcrypt.cpp(27) : see declaration of 'make'
xcrypt.cpp(37) : error C2362: initialization of 'make' is skipped by 'goto end'
        xcrypt.cpp(27) : see declaration of 'make'
xcrypt.cpp(37) : error C2362: initialization of 'read' is skipped by 'goto end'
        xcrypt.cpp(19) : see declaration of 'read'

the code:

Code:

---

#include<iostream.h>
#include<fstream.h>

int main()
{
        char Filename[50], chr;
        int Key;
       
        cout<<"Enter Filename To Encrypt";
        cin>>Filename;
        cout<<"Enter Key # (1-10)";
        cin>>Key;

        if(Key>10){ // Checks if key is no greater then 10
                cout<<"Invalid Key";
                goto end;
        }
       
        ifstream read;
        read.open(Filename,ios::in);

        if(!read){ // Checks if file exists
                        cout<<"Unable To Open File";
                        goto end;
        }
        ofstream make; // Creats file "Encrypted.tmp"
        make.open("Encrypted.tmp",ios::out);

        while(read)
        {
                read.get(chr); // Gets chr
                chr = chr + Key; // Takes the char and adds to it 'Key'
                make<<chr; // Writes Encrypted chr
        }

        end:
        return 0;

}

It seems to be choking cuz you are declaring an ifstream and an ofstream after a possible jump....

If you must use goto for this, put the declarations at the top of the code block

Code:

---

#include<iostream.h>
#include<fstream.h>

int main()
{
        char Filename[50], chr;
        int Key;
        ifstream read;
        ofstream make; // Creats file "Encrypted.tmp"
       
        cout<<"Enter Filename To Encrypt";
        cin>>Filename;
        cout<<"Enter Key # (1-10)";
        cin>>Key;

        if(Key>10){ // Checks if key is no greater then 10
                cout<<"Invalid Key";
                goto end;
        }
       
       
        read.open(Filename,ios::in);

        if(!read){ // Checks if file exists
                        cout<<"Unable To Open File";
                        goto end;
        }
       
        make.open("Encrypted.tmp",ios::out);

        while(read)
        {
                read.get(chr); // Gets chr
                chr = chr + Key; // Takes the char and adds to it 'Key'
                make<<chr; // Writes Encrypted chr
        }

        end:
        return 0;

}

thank you that worked
