Putting two pieces of code together help

[gibbsy619]

Just finished some prototypes and looking to put them all together but can't seem to do it, they are completely identical pieces of code with different variable names but I am not able to 'stick' them together, all the program says is that I have redefined a lot of things but without it the program won't work, any help most appreciated.
#include <iostream>
#include <string>
using namespace std;

bool valcheck(string message)
{
int k = 0;
for(int i = 0; i < message.size();i++)
{
if((message[i] < 97 || message[i] > 122) && message[i] != 32)
return false;
}
for(int j = 0; j < message.size();j++)
{
if(message[j] < 122 && message[j] > 97)
k++;
}
if(k == 0)
return false;
return true;

}
int main()
{
string message;
cout << "Please enter a message CONTAINING only letters and spaces" << endl;
getline(cin, message);
for(int i = 0; i < message.size();i++)
message[i] = tolower(message[i]);
while(valcheck(message) == false)
{
cout << "Please try again" << endl;
cout << "Please enter a message CONTAINING only letters and spaces" << endl;
getline(cin, message);
}
cout << "Input Validation Successful" << endl;
cout << message << endl;
return 0;
}
bool valcheck2(string offset)
{
int k = 0;
for(int i = 0; i < offset.size();i++)
{
if(offset[i] < 47 || offset[i] > 58)
return false;
}
for(int j = 0; j < offset.size();j++)
{
if(offset[j] < 58 && offset[j] > 47)
k++;
}
if(k == 0)
return false;
return true;
}
using namespace std;
int main()
{
string offset;
cout << "Please enter an offset CONTAINING only numbers" << endl;
getline(cin, offset);
while(valcheck2(offset) == false)
{
cout << "Please try again" << endl;
cout << "Please enter offset CONTAINING only numbers" << endl;
getline(cin, offset);
}
int numberoffset = atoi(offset.c_str());
numberoffset = numberoffset % 26;
cout << "Input Validation Successful" << endl;
cout << numberoffset << endl;
return 0;
}

Hi,

I am pretty sure you cant use int main() more than once, please read more about functions

http://www.cplusplus.com/doc/tutorial/functions/

just use one int main() and also define function prototype for ease of code :)

HOPE IT HELPS
