C++基础-数据类型
本文主要讲述C++基本数据类型,如何引用这些基本数据类型.
1.在data.h中声明
//data.h文件 #include "stdio.h" #include <string> #in !undefined(AFX_123) int age; short height; long distance; float weight; double area; char c; char* p; char radio[10]={"hello C++"}; bool result; #define AFX_123 #endif
2. 在data.cpp中定义和引用
#include "data.h" #include "iostream.h" void main() { //开始定义 age=10; height=175; distance=3; weight=145.1; area=7.5211; c='D'; p=radio; cout<<"age="<<age<<endl; cout<<"height="<<height<<endl; cout<<"distance="<<distance<<endl; cout<<"weight="<<weight<<endl; cout<<"area="<<area<<endl; cout<<"字符c="<<c<<endl;
cout<<"数组radio"<<radio<<endl;
cout<<"指针数据"<<p<<endl; }
