Data type Conversions

Int and float

Code:

#include <iostream>

#include <conio.h>

using namespace std;

int main (int argc, char *argv[])

{

    int a=4,c;

    float b=3.5,d;

    d=a;

    c=(int)b;

    cout <<" a value is   : "<< a << endl;

    cout <<" b value is   : "<< b << endl;

    cout <<" d value float type conversions : "<< d << endl;

    cout <<" c value int type conversions : "<< c << endl;

  getch();

  return 0;

}
