Capitalizing first letter of every word in C++

So I'm trying to get this done by using bool and then some simple if statements but for some reason it either doesn't capitalize anything or capitalizes everything if I remove the last if statement. I don't know if I set up the bool parameters correctly..

#include <cstdio>
#include <iostream>
using namespace std;

int main ()
{


int c = cin.get() ; 
bool fletter = true ;
if(c == ' ' || c == '\t' || c == '\n');
   // fletter = true;


do
{

if (fletter = true);    {
    c = toupper(c);
    fletter = false;
}


{if (fletter = false);

  c = tolower(c);

}

cout.put(c) ;
c = cin.get() ;

  }while ( !cin.eof()) ;

}
