Type casting (or) Type conversion

                      The process of converting one datatype to another datatype is called as type casting or type conversion.

                    In C Language type conversion is an arithmetic expression will be done automatically. This is called implicit conversion. If we want to store a value of one datatype into a variable of another datatype, we must caste the value to be stored by preceding it with the type name in parenthesis. This is called explicit conversion or type casting.

Eg:

        int a, b;

        float c,d;

        a=5;

        b=2;

        c=a/b;        c=2.00        Automatic (or)  implicit conversion

        d=(float)a/b;    d=2.50    Type casting (or) explicit conversion

Program:

#include<stdio.h>

#include<conio.h>

void main()

{

    int a, b;

    float c, d;

    clrscr();

    printf("Enter any Two Numbers : ");

    scanf("%d%d", &a, &b);

    c=a/b;

    d=(float)a/b;

    printf("c=%.2f", c);

    printf("\nd=%.2f", d);

    getch();

}

Output:

Enter any Two Numbers : 5  2

c=2.00

d=2.50
