Type casting is used when you want to convert the value of a variable from one type to another.
Type casting does not change the actual value of the variable.
#include <stdio.h>
main()
{
double d1 = 1234.56;
int i1=456;
printf("the value of d1 as int without cast operator %d\n",d1);
printf("the value of d1 as int with cast operator %d\n",(int)d1);
printf("the value of i1 as double without cast operator %f\n",i1);
printf("the value of i1 as double with cast operator %f\n",(double)i1);
i1 = 10;
printf("effect of multiple unary operator %f\n",(double)++i1);
i1 = 10;
printf("effect of multiple unary operator %f\n",(double)- ++i1);
i1 = 10;
printf("effect of multiple unary operator %f\n",(double)- -i1);
i1 = 10;
printf("effect of multiple unary operator %f\n",(double)-i1++);
}
the value of d1 as int without cast operator 1889785610
the value of d1 as int with cast operator 1234
the value of i1 as double without cast operator 1234.559570
the value of i1 as double with cast operator 456.000000
effect of multiple unary operator 11.000000
effect of multiple unary operator -11.000000
effect of multiple unary operator 10.000000
effect of multiple unary operator -10.000000
