Consider this program: Q. Why it is returning size of var as 4 where var is an integer

Question

cout << "char: " << sizeof(char) << endl;
cout << "int: " << sizeof(int) << endl;
cout << "float: " << sizeof(float) << endl;
cout << "double: " << sizeof(double) << endl;
int var = 50;
cout << "var: " << sizeof(var) << endl;

/* Outputs
char: 1
int: 4
float: 4
double: 8
var: 4
*/
