My program compiles correctly but when I choose one of the options nothing comes up, and I cannot figure out why. If anyone can please help me that would be awesome.... I know my while loop in the main is not completed yet.
I believe my problem is either in the loadlist or the print function.
Please help
here is my code
#include <iostream>
#include <fstream>
#include <iomanip>
#include <string>
using namespace std;
//Struct
struct PublicOfficial
{
string name;
string sob;
int code;
int presorder;
int firstpterm;
int lastpterm;
int vpresorder;
int firstvpterm;
int lastvpterm;
PublicOfficial *nextofficial;
};
//Globals
ifstream infile;
//Prototypes
void LoadList ( PublicOfficial *&firstofficial );
void addOfficial ( PublicOfficial *&firstofficial, PublicOfficial *nextofficial );
void printall ( PublicOfficial *firstofficial, PublicOfficial code);
void printoneterm ( PublicOfficial *firstofficial );
int menu();
int main()
{
PublicOfficial *firstofficial = NULL;
PublicOfficial code;
int choice;
//Calling LoadList
LoadList ( firstofficial );
//Calling Menu
choice = menu();
while ( choice != 7 )
{
if ( choice == 1 )
{
printall ( firstofficial, code );
}
else if ( choice == 2 )
printall ( firstofficial, code );
else if ( choice == 3 )
printall ( firstofficial, code );
else if ( choice == 4 )
printoneterm ( firstofficial );
//Calling Menu
menu();
}
return 0;
} // End of Main
