Thread: minor error need help on

Code:

#include <ctype.h>
#include <iomanip.h>
#include <fstream.h>
#include <string>
#include <iostream.h>

void printdata(char, double);

int main (void)
{
int freqcount[26] = {0};  //array to hold letter values
int totalcount = 0;       //initializes total count to value '0'
string InFileName;
cout <<"\nEnter name of file to process: "; //prompts user for input filename
getline(cin,InFileName); 
ifstream inStream;inStream.open(InFileName.data());
if (!inStream.is_open())
{
  cerr << "\nError opening " << InFileName << endl;
  return -1;
}
double percent;                  
double i;
char Ch;
inStream >> Ch;
while (!inStream.eof())
{
 Ch = toupper(Ch);
 if ((Ch <= 'Z') && (Ch >= 'A'))
  { 
   totalcount++;
   freqcount[Ch - 65]++;
  }
 inStream >> Ch;
}
cout << "\n" << "Char       %" << endl
<< "===================================================================\n";
for (int k=0; k<=25; k++)
 {
  percent = freqcount[k]*100.0/totalcount;
  printdata(char(k+65), percent);
 }
cout << endl << endl << "Number of letters = " << totalcount << endl;
}

void printdata(char Ch, double percent)
{
double i;
cout << "  "<< Ch << "       " << setiosflags(ios::showpoint | ios::fixed
       | ios::right) << setprecision(1) << setw(5) << percent;
for (i=2*percent; i>0.5; i--) cout << '*'; cout << endl;
}

and my errors are as follows

test.c: In function 'int main()':
test.c:13: error: 'string' undeclared (first use this function)
test.c:13: error: (Each undeclared identifier is reported only once for each function it appears in.)
test.c:13: error: parse error before ';' token
test.c:15: error: 'InFileName' undeclared (first use this function)

any help would be appreciated.

might be beaten to this but here goes...

Code:

#include <ctype.h>
#include <iomanip>
#include <fstream>
#include <string>
#include <iostream>

using namespace std;

You might need a

Code:

cin.get()

as well near the end of main to pause the program.

i still get the same errors.

Try compiling in .cpp

thank you for all of the advice i got it to work.
