int sum = 17, count = 5;
double mean;
mean = (double) sum / count;
printf("Value of mean : %f\n", mean );

}what is typecasting
Assigning a value of one type to a variable of another type is
known as Type Casting.
Auto-boxing; is a process when you take a primitive value and
assign into wrapper class object.
Un-boxing; is a process when you take Wrapper class object
and convert to primitive.typecasting java

// You can typecast to convert a variable of one data type to another.
// Wide Casting converts small data types to larger ones.
// Narrow Casting converts large data types to smaller ones.
// Java can automatically Wide Cast.
// Java will throw an error when trying to automatically Narrow Cast.
// This is because data is often lost when Narrow Casting.
// Narrow Casting must be done manually.
//Wide Cast:
int SomeNumber = 5;
double WideCastedNumber = (double)SomeNumber;
//Narrow Cast:
double SomeNumber = 5.39;
int NarrowCastedNumber = (int)SomeNumber;
//Note: The data that holds the decimal places will be lost!cast java
JAVA: Example of cast:
int SomeNumber = 5; //int
double WideCastedNumber = (double)SomeNumber; //from int to double
double myDouble = 9.78;
int myInt = (int) myDouble; // from double to intType Casting
#include <iostream>
using namespace std;
int main() {
// initializing a double variable
double num_double = 3.56;
cout << "num_double = " << num_double << endl;
// C-style conversion from double to int
int num_int1 = (int)num_double;
cout << "num_int1 = " << num_int1 << endl;
// function-style conversion from double to int
int num_int2 = int(num_double);
cout << "num_int2 = " << num_int2 << endl;
return 0;
