一、变量的作用域 C语言根据变量作用域的不同,将变量分为局部变量和全局变量。 1.局部变量 1> 定义:在函数内部定义的变量,称为局部变量。形式参数也属于局部变量。 2> 作用域:局部变量只在定义它的函数内部有效,即局部变量只有在定义它的函数内部使用,其它函数不能使用它。 2.全局变量 1> 定义: ...
'float' variable declaration float weight; /*to store weight in kilogram and gram*/ 'float' constant declaration const float PI=3.14f; /*to store value of PI as 3.14*/ These are the basic/primitive data types in C language, there are other data types too, they are the enhanced version...
