c++ types of variables code example

Example 1: c++ declare variable

std::string str = "text";	// stores a string
int    foo = 3;				// stores any integer
float  bar = 3.14;			// stores 32 bit number
double baz = 3.14159265;	// stores 64 bit number

Example 2: variabvles in c++

#include <iostream>

using namespace std
  
int main{
	int x = 3;
    float g = 4.0;
    long h = 1234567;
    double j = 1237886.099;
    cout<<x<<endl;
    cout<<h<<endl;
    cout<<g<<endl;
    cout<<j<<endl;
}

Example 3: data types in c++

int myNum = 5;               // Integer (whole number)
float myFloatNum = 5.99;     // Floating point number
double myDoubleNum = 9.98;   // Floating point number
char myLetter = 'D';         // Character
bool myBoolean = true;       // Boolean
string myText = "Hello";     // String
