Process Control1. Conditional statementsGive me a chestnut:If x>5 { return 1;} else{ return 0;}Attention:? Conditional statements do not need parentheses to enclose conditions ();?

After the if, the conditional statement can be added before the variable initialization statement, use; interval;? In a function that has a return value, the "final" return statement is
The Go language is a static type of programming language, so when the compiler compiles, you need to know the type of each value so that the compiler knows how much memory to allocate for that value and knows what the allocated memory represents.There are many benefits to knowing the type of value in advance, such as the compiler can use these values reasonably, can further optimize the code, improve the efficiency of execution, reduce bugs and so on.
Go language type ConversionType conversions are used to convert a variable of one data type to a variable of another type, and the basic format for the Go language type conversion is as follows:type_name(expression)Type_name is a type, and expression is a formula.InstanceThe following example converts a shape to a floating-point type, evaluates the result, and assigns the result to a floating-point variable
