三大基本类型（整型，浮点型，字符型）局部变量#include#include
int _tmain(int argc, _TCHAR* argv[])
{
//局部变量
int nNum = 1;
float fNum = 25;
char ch = 'A';
printf("int %d,float %f,char %c",nNum,fNum,ch);
return 0;
}
x86_debug：1234法找main函数通过三个函数调用来获取三个参数，第一个是参数数量，第二个是参数数组，第三个环境变量地址数组地址x86_release版本：23法找main函数
x64_debug：1234法x64_release：25法
全局变量：#include
#include
//全局变量，静态变量
int g_nNum = 1;
static int g_nCount = 2;
float g_fNum = 25;
char g_ch = 'A';
int _tmain(int argc, _TCHAR* argv[])
{
printf("int %d,float %f,char %c",g_nNum,g_fNum,g_ch);
return 0;
}

#include
int _tmain(int argc, _TCHAR* argv[])
{
int nArr = { 1,2,3,4,5 };
int n = 2;
nArr = 20;
return 0;
}
结构体#include
#include
struct MyStruct {
int nNum;
float fNum;
char chA;
};
void Print(MyStruct stc) {
printf("int %d,float %f,char %c", stc.nNum, stc.fNum, stc.chA);
}
int _tmain(int argc, _TCHAR* argv[])
{
MyStruct stc = { 1,2.2,'A' };
stc.fNum = 5.5;
Print(stc);
return 0;
}
常量#include
#include
#define SIZE 100
const int g_nCount = 1000;
enum eData
{
enum_TYPE_1 = 1,
enum_TYPE_1 = 2,
enum_TYPE_1 = 3,
};
struct sData {
int n;
float fNum;
char chA;
};
int _tmain(int argc, _TCHAR* argv[])
{
bool bRet = true;
const int nCount = SIZE;
const char* szHello = "Hello 15PB";
const eData data = enum_TYPE_1;
const float fNum = 1.5;
const sData stc = { 1,2.0,'1' };
return 0;
}
字符串#include
#include
int _tmain(int argc, _TCHAR* argv[])
{
char szStr = { "szStr Hello 15PB" };
wchar_t szWchar = L"szWchar Hello 15PB";
char* szHello = "szHello* Hello 15PB";
return 0;
}
