  #include <ctype.h>
  #include <fstream>
  int main()
  {
  ifstream infile("input.txt");
  ofstream outfile("ouput.txt");
  string line;
  while (getline(infile,line))
  {
  for (int i=0; i<line.length(); i++)
  
  if (i==0 || line[i-1] == ' ' && isalpha(line[i]))
  line[i] = toupper(line[i]);
  outfile << line << endl;
  }
   
  }

You need to tell the compiler which namespace to use.

 

Add this line after your two includes...

 

using namespace std;

 

Cheers,

 

Matt
