Help with my first program

[Gubbedelux]

This is my code so far

I want the program to chose between a diameter from 0.5 to 3 mm or 3 to 6mm and pick the correct tolklass and display it in cout diam and tolklass.
If i pick a diameter between 0.5 to 3 the tk would be 0.03
If i pick a diameter between 3 to 6 the tk would be 0.07
Can anyonr help me to solve this please.


/* Toleransklass*/
#include <stdlib.h>
#include <iostream>
#include <string>
#include <cfloat>
#include <iomanip>

using namespace std;

int main()
{
string tk;
float diam,tolklass;

cout << "Enter diameter/l\x84ngd ";

cin>> diam;
cout << "f m c eller v ";
cin>> tk;

if(diam<=3 && diam >=0.50)
if (tk=="f")tolklass =0.01;
if (tk=="m")tolklass =0.02;
if (tk=="c")tolklass =0.03;
if (tk=="v")tolklass =0.04;

else if(diam<=6 && diam >=3)
if (tk=="f")tolklass =0.05;
if (tk=="m")tolklass =0.06;
if (tk=="c")tolklass =0.07;
if (tk=="v")tolklass =0.08;
cout <<"\n\n";
cout <<"Diameter "<< setprecision (4) << diam << " " << setprecision (4) <<tolklass;
cout <<"\n";

system ("pause");
return 0;
}

Wrap these

if (tk=="f")tolklass =0.01;
if (tk=="m")tolklass =0.02;
if (tk=="c")tolklass =0.03;
if (tk=="v")tolklass =0.04;

and these

if (tk=="f")tolklass =0.05;
if (tk=="m")tolklass =0.06;
if (tk=="c")tolklass =0.07;
if (tk=="v")tolklass =0.08;

in braces

{
...
}
