Write a program to find Energy (Conservation) Formula in C++

Write a program which take Energy (conservation)
 value of m and c from user and return value of E along its unit.
E = mc^2


Input:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

#include <iostream.h> #include <conio.h> int main() { cout << " Energy (conservation) Formula is E = m*c^2 \n"; float m, c, c2, E; cout << "Enter the value of m <mass>?\n"; cin >> m; cout << "Enter the value of c <speed of light>?\n"; cin >> c; c2 = c*c; E = m*c2; cout <<"\tE = "<< E << " kg m^2/s^2"<< endl; getch(); return 0; }// end main

Output

Energy (conservation) Formula is E = m*c^2
Enter the value of m <mass>?
4.56
Enter the value of c <speed of light>?
3.456
      E =54.4643 kg m^2/s^2
