Return to first line...
hello everyone,
I was wondering if there is a way to return to the first line of C++ code? So say the program executes and everything goes well then at the last line of code the programs starts over at line one. Any help would be greatly appreciated. Thanks in advance, Doug Mellon

Well there is a few ways to do this, you could put the program itself in a loop that exits when the user terminates it or you could just make a cin statement and use the goto function. The first is far more professional but both work fine.
While Loop ("Please excuse the simplicity its late") Code:
#include <cstdlib>
#include <iostream>
using namespace std;
int main()
{
int a=0,i=0;
while (i != 1)
{
cout<<"Run the program\n";
cout<<"Would you like to exit or start over\n"
<<"0 = start over || 1 = exit\n";
cin>>i;
}
system("PAUSE");
return EXIT_SUCCESS;
}
Using the goto statement. Code:
#include <cstdlib>
#include <iostream>
using namespace std;
int main()
{
int a=0,i=0;
top:
cout<<"Run the program\n";
cout<<"Would you like to exit or start over\n"
<<"0 = start over || 1 = exit\n";
cin>>i;
if(i==0)
{
goto top;
}
else
{
system("PAUSE");
return 0;
}
system("PAUSE");
return EXIT_SUCCESS;
}
Now none of these example have any error checking so beware =)

if you're really sick, you could even simply call the main() function...
Doing this multiple times will fill up your memory pretty fast though, as it is recursive. The do-while loop is your best bet.
