Missing cout


Me trying some C.. cout in specific, thats what i remembered:

#include <stdio.h>
// -- Just the above or with all the below ones, no change 
#include <stdio_ext.h>
#include <stdlib.h>
#include <wchar.h>
//#include <iostream>	// I assume its the same anyway?
//#include <iostream.h> // But since these fail, and cout still is missing, i have no idea
#include <string.h>
#include <strings.h>
#include <stropts.h>
//#include <stream.h>
//#include <io.h>
#include <stdint.h>
#include <stdfix.h>
#include <unistdio.h>
#include <libio.h>
//#include <input.h>
//#include <sdbout.h>
//#include <system.h>
//#include <errors.h>
//#include <options.h>
//#include <filenames.h>
//#include <shout.h>
//#include <system.h>

//#include <regexp.h>
//#include <keyutils.h>

void main(){
	cout "Hello"; 		// Upon inital error msg, recalled this was wrong
	cout << "Hello"; 	// So tried this one
	std::cout << "Hello";	// This one's from a guide but fails too
	std:cout << "Hello";	// didnt see that before, but since above failed because of '::'

I've seen the bold include lines associated with it, but it fails:
0 ~/prjs/c-learnings/1-output $ build-it cout

+ gcc -o cout cout.c
cout.c: In function 'main':
cout.c:30:2: error: 'cout' undeclared (first use in this function)
  cout "Hello";   // Upon inital error msg, recalled this was wrong
cout.c:30:2: note: each undeclared identifier is reported only once for each function it appears in
cout.c:30:7: error: expected ';' before string constant
  cout "Hello";   // Upon inital error msg, recalled this was wrong
cout.c:32:6: error: expected expression before ':' token
  std::cout << "Hello"; // This one's from a guide but fails too
cout.c:33:2: error: duplicate label 'std'
  std:cout << "Hello"; // didnt see that before, but since above failed because of '::'
cout.c:32:2: note: previous definition of 'std' was here
  std::cout << "Hello"; // This one's from a guide but fails too
+ RET=1
+ '[' 0 -eq 1 ']'
+ set +x

Any ideas, thank you

cout is a C++ feature not found in C.
