C++, OPENGL and translate() function which throws an error for its arguments

I'm concerned mainly with glm library. I want to translate a vector+matrix, using glm::translate, but it throws errors:

I have the following code:

#define GLEW_STATIC
#include <stdio.h>
#include <iostream>
#include <fstream>
#include <vector>
#include <string>
#include <GL\glew.h>
#include <GL\GLU.h>
#include <GL\glut.h>
#include <glm.hpp>
#include <GL\gl.h>
#include <gtx\transform2.hpp>
#include <GLFW\glfw3.h>



using namespace std;
using namespace glm;

int main()
{
    if (!glfwInit())
    {
        fprintf(stderr, "Failed to initialize GLFW\n");
        return -1;
    }



    // defining the matrices
    glm::mat4 myMatrix = glm::translate(10f,0.0f,0.0f);
    glm::vec4 myVector(10.0f, 10.0f, 10.0f, 0.0f);
    glm::vec4 transformedVector = myMatrix * myVectors; // multiplication  

    return 0;
}

When I execute the code, I get the following errors:

error C2059: syntax error : 'bad suffix on number'
error C2146: syntax error : missing ')' before identifier 'f'
error C2784: 'glm::detail::tmat4x4<T,P> glm::translate(const glm::detail::
tvec3<T,P> &)' : could not deduce template argument for 'const glm::detail::tvec3<T,P> &' from 'int'

and a bunch of more errors.

Using the @lazyCoder's solution, I eliminated many errors. Though, I get an error about glm::translate() which is about arguments:

 error C2780: 'glm::detail::tmat4x4<T,P> glm::translate(const glm::detail::tvec3<T,P> &)
' : expects 1 arguments - 3 provided
    1>          c:\opengl\glm-0.9.5.4\glm\glm\gtx\transform.hpp(61) : see declaration of
 'glm::translate'

    error C2780: 'glm::detail::tmat4x4<T,P> glm::translate(const glm::detail::tmat4x4<T,P>   
 &,const glm::detail::tvec3<T,P> &)' : expects 2 arguments - 3 provided    
    1>          c:\opengl\glm-0.9.5.4\glm\glm\gtc\matrix_transform.hpp(86) : see declaration of 'glm::translate'

This may be a recent change (using glm 9.61 I believe), and I don't know if it's relevant for this discussion anymore, but glm::translate() appears to take arguments glm::mat4x4 and glm::vec3 respectively.

Thusly, when I had a similar error as above I changed my expression from 

glm::translate(10.f,0.f,0.f)

to 

glm::translate(glm::mat4x4(),glm::vec3(10.f,0.f,0.f)).

replace the first argument of the translate call with 10.f the compiler complains about an improper suffix on the number, or to quote the g++ error message invalid suffix "f" on integer constant

follow up to the consecutive error I don't now glm but it seems that translate takes a vec3 as input and not 3 arguments so try 

translate(glm::vec3(10.f, 0.f, 0.f))
