Document Summary
C++ is a strongly typed language every variable before you can use it must be explicit declared/ defined. You don"t need to declare a variable: simplify the problem. Make sure it works @ this state. Does it matter where i declare a variable? declare variables closest place to where we use it. Rule #1: when you declare a variable the scope of the variable section in which it lives determined by { } Depending on which curly brackets you declare. {} executed > variable created in within {} only in which they are defined. All sub blocks can also see the variable but not the code outside the block > after executed gets destroyed double prem = 50; is a shortcut for prom = 50; ___________________________________ double vs int if you know for a fact that the age an never be . 5 (26. 5)
