C++ Examples - Creating Different Types of Variables

The following example demonstrates how to create variables of different types:

Example

#include<iostream>
#include<string>
using namespace std;

int main()
{
    // Create variables
    int myNum = 5;              // Integer
    float myFloatNum = 5.99;    // Floating point number
    double myDoubleNum = 9.98;  // Double precision floating point number
    char myLetter = 'D';        // Character
    bool myBoolean = true;      // Boolean
    string myString = ""; // String

    // Print variables
    cout << "int: " << myNum << "n";
    cout << "float: " << myFloatNum << "n";
    cout << "double: " << myDoubleNum << "n";
    cout << "char: " << myLetter << "n";
    cout << "bool: " << myBoolean << "n";
    cout << "string: " << myString << "n";
    return 0;
}

The output of the above program is:

int: 5
float: 5.99
double: 9.98
char: D
bool: 1
string:
