Write a program of Memory Constant

Write a program that Demonstrates three ways to use constant in C++

Input:

1 2 3 4 5 6 7 8 9 10 11 12

#include <iostream.h> #include <conio.h> #define PI 3.1415926536 int main() { const double pi = 3.1415926536; cout << "Defined Constant PI:" << PI << '\n'; cout << "Memory Constant pi:" << pi << '\n'; cout << "Liteat Constant : " << 3.1415926536 << '\n'; getch(); return 0; } //End main

Output:

 Defined Constant PI: 3.14159
 Memory  Constant pi: 3.14159
 Liteat  Constant :   3.141592
