C++ Variable Types



« Previous Tutorial Next Tutorial »


In C++, a variable is basically a named storage that our programs can manipulate. Each and every variable in C++ has particular type, determines the layout and size of the memory of the variable, and the value's range that can be stored within that memory.

C++ Variable Type Example

Here is an example, uses many types of variables in C++:

/* C++ Variable Types */

#include<iostream.h>
#include<conio.h>
void main()
{
	clrscr();

	int i;
	float f;
	char c;
	double d;
	signed int si;
	unsigned int ui;

	cout<<"Enter any integer value: ";
	cin>>i;
	cout<<"You have "<<i;
	cout<<"\n\nEnter signed integer value: ";
	cin>>si;
	cout<<"You have "<<si;
	cout<<"\n\nEnter unsigned integer value: ";
	cin>>ui;
	cout<<"You have "<<ui;
	cout<<"\n\nEnter a floating-point value: ";
	cin>>f;
	cout<<"You have "<<f;
	cout<<"\n\nEnter a character: ";
	cin>>c;
	cout<<"You have "<<c;

	getch();
}

Here is the sample run of this C++ program:

C++ also allows to define various other types of variables, which we will cover in subsequent chapters like pointers, arrays, references, structures, and class, etc.
