c++ to c conversion

closed account (G8k4izwU)
dear members would some one help me to convert the following code from c++ to c ;


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



float momentum(float m , float v)
{
float mom = m * v;
return mom;

}


float work (float f , float d)
{
float wor = f * d;
return wor;

}


float energy (float m , float v)
{

float ene;
ene = 0.5 *(m * (v*v));

return ene;


}


int main ()
{
cout<<"\t\t========select the formulla======== \n";
cout<<"1- Momentum\n";
cout<<"2- Work\n";
cout<<"3- Energy\n";
cout<<"4- Go back\n";
cout<<"\n\n\nYour option [ ]\b\b";



int select ;
float v1 , v2;
cin>>select;

switch (select ){

case 1:
system("cls");
cout<< "Enter mass value : \n";
cin>>v1;
cout<< "Enter velocity : \n";
cin>>v2;
cout<<"Momentum is = "<<momentum(v1,v2)<<" kg-m/sec\n\n";
break;

case 2:
system("cls");
cout<< "Enter force value : \n";
cin>>v1;
cout<< "Enter distance value in meters : \n";
cin>>v2;
cout<<"Work is = "<<work(v1,v2)<<" joule(j)\n\n";
break;


case 3:
system("cls");
cout<< "Enter mass value : \n";
cin>>v1;
cout<< "Enter velocity : \n";
cin>>v2;
cout<<"Energy is = "<<energy(v1,v2)<<" joule(j)\n\n";
break;


case 4 :
system ("cls");

cout<<"========Testahbel enta no back Tshaaah astgfur allah========\n\n";
cout<<"press 'y' to exit\n\n";
char yes ='y';
if(yes == 'y')
break;


}

system("pause");
return 0;
}
===================================================

thanks in advance

Could I shortly ask that what's this : %d I've never learnt C before.

That is the int decimal format specifier for the printf and scanf family of functions.
