Thread: need a clue

hi everybody...
i want to test to see if an input string
is part of an array of srtings
for example
if I declare a string of 8 months:

Code:

const char *months[8] = {"January", "February", "March", "April", "May", "June", "July", "August"};

how do i test if a cin'd month name is part of that set
(so i can have a trap if invalid data is entered)
I have tried many combination of string compare and am not having any luck
thanks
surfer grrl

sorry i have tried EVERY imaginable combo of that am am still getting;

Code:

C:\Program Files\Microsoft Visual Studio\MyProjects_M\Sem_2\4_1\4_1.cpp(125) : error C2664: 'strcmp' : cannot convert parameter 1 from 'char' to 'const char *'

here is the entire program ...if you can:PLEASE help!!

Code:

# include <iomanip>
#include <string>
# include <fstream>
# include <iostream>
using namespace std; 

class Month{
public:
 void Month::Load(Month[]);
 int Month::calcdays(const Month[], int);
 int Month::calcdays(const Month[], char*);
 void Month:: printResult(const Month[],int, int); 


 int MonthNumber;
 char MonthName[10];
 char MonthAbrv[5];
 int MonthDays;
 }; 

char month[12][10] = { "January", "February", "March", "April", "May", "June", "July", "August"};
const MAXMONTHS = 12; 

//extern file with Month load data
ifstream infile("C:\\CODE\\INF\\3abc\\IF3abc.TXT"); 

int main ()
{ 

Month AM[MAXMONTHS];
int nm = 0;
int total = 0;
char month[10]; 

if (!infile) 
{
cerr << "Cannot open input file" << endl;
}//if
 else 
 { 

 AM[MAXMONTHS].Load(AM); 

  cout << "\n\n" << setw(55) << "Year-To-Date Number of Days Calculation" << endl; 

 for (int i = 0; i< MAXMONTHS; i++)
 {
  cout << "\n\n" << setw(55) << "Enter Number of Month (i.e. Dec = 12): ";
  cin >> nm;
  
  total = AM[MAXMONTHS].calcdays(AM, nm);
  if (total ==0)
  {}//don't print result if entry is invalid
  else
  {AM[MAXMONTHS].printResult(AM,nm, total);}
  
  
  cout << "\n\n" << setw(61) << "Enter Name of Month (capitalize 1st letter): ";
  cin >> month;
 
  total = AM[MAXMONTHS].calcdays(AM, month);
 

  AM[MAXMONTHS].printResult(AM, nm, total);
  

 }//for 

}//else 

return 0; 

}//main 

  

//data load-----------------------------
void Month::Load(Month AM[])
//in:AM; out:none
{ 
 for (int n = 0; n < 12; n++) {
 infile >> AM[n].MonthNumber;
 infile >>(AM[n].MonthName); 
 infile >>(AM[n].MonthAbrv);
 infile >>(AM[n].MonthDays); 

 }//for 
}//fx load 


//calculate days 1-----------------------
int Month::calcdays(const Month AM[], int nm)
//in:AM, nm; out:none
{
 int total=0;
 int n = 0;
if (nm < 1 || nm > 12) 
  {
   cout << "\n\n" << setw(33) << "<<Invalid Entry>>";
   return 0;
   
  }//if
  else
  {
   while (AM[n].MonthNumber <= nm) 
   {
   total += AM[n++].MonthDays;
   }//while 

   return total;
  }//else 

}//fx calcdays 1 

//calculate days 2--------------------------
int Month::calcdays(const Month AM[], char *month)
//in:AM, month; out:none
{


int total=0; 
for (int i =0; i < MAXMONTHS; i++)
{
	
    if ( strcmp(month[i], *month) == 0 ) 
	{
		cout << "\n\n" << setw(33) << "<<Invalid Entry>>";
	return 0;
	}

 for (int n = 0; n < 12; n++) 
 {
 total += AM[n].MonthDays;
 if ( strcmp(month,AM[n].MonthName ) == 0)
 break;
 }//for


 return total; 
}
}//fx calcdays 2 

  

void Month:: printResult(const Month AM[], int nm, int total) 
//in:AM, nm; out:none
{ 

   cout << "\n\n" << setw(63) << "The total days in the year up to and including "
  <<AM[nm-1].MonthName<< " = " 
  <<total<<endl; 

}//fx PrintResult

see if the input month is one of the valid months of the yr - if not return 0 or say "entry is invalid"

Your code

Code:

if (strcmp(month[i], *month) == 0)

Magos code

Code:

if(strcmp(Month[i], MonthToCheckWith) == 0)
