疑问： mysql的字段，unsigned int(4), 和unsinged int(5), 能存储的数值范围是否相同。如果不同，分别是多大？

android.os.Parcelable { public static final android.os.Parcelable$Creator *; } 3.项目打包 右键工程，选择androidtools-export unsinged

struct{u_short s_w1,sw_2;}S_un_w; u_long S_addr; }S_un; }; 32位与aa.bb.cc.dd之间的转换，可以通过下面函数完成 unsinged
using namespace std; 3 int main() 4 { 5 int a[]={1,2,2,3,4}; 6 int n=sizeof(a); 7 unsinged
length is smaller than 254 bytes, it will only consume a single * byte representing the length as an unsinged...length is smaller than 254 bytes, it will only consume a single * byte representing the length as an unsinged
dword ptr [ebp-2Ch],0 004010ED mov eax,dword ptr [ebp-2Ch] 004010F0 mov dword ptr [ebp-10h],eax //pB=(unsinged
讲解扫雷的界面 刚开始我们需要用函数dacd打印游戏的菜单，do-while循环输入1开始游戏，输入0的话while表达式为假循环结束， srand((unsinged int)time(NULL))
size_t size_t主要用于计数，他就是一个unsinged int的重定义. 如sizeof函数返回值类型即为size_t。
s,char **endp) 将字符串s前缀转换为double型 7 long strtol(const char*s,char **endp,int base) 将字符串s前缀转换为long型 8 unsinged...long strtol(const char*s,char **endp,int base) 将字符串s前缀转换为 unsinged long型 9 int rand(void) 产生一个0~RAND_MAX
