// Solidity define many types of especial units or variables lets check the units here
// then we will talk about global variables & functions in next lecture
contract Units {
// Ether Units are available as a global variables
// wei, finney, szabo & ether are variable themself
// variable can not be named as the ether, finney, szabo, wei
// use http://ether.fund/tool/converter for more such conversion
bool isEqual = (2 ether == 2000 finney);
// Time Units are also availabel in solidity like this
// seconds, minutes, hours, days, weeks, years are all available at time units to be used
// can be used anywher in the program like mentioned below
bool isEqual = (1 == 1 seconds);
bool isEqual = (1 minutes == 60 seconds);
bool isEqual = (1 hours == 60 minutes);
bool isEqual = (1 days == 24 hours);
bool isEqual = (1 weeks = 7 days);
bool isEqual = (1 years = 365 days);
Define consutruct here
function Units(uint initialCoins) {
// Initialize state variables here
}
}
