本文详细介绍了C++中char, short, int, long, float, double以及uchar等基本数据类型的sizeof运算结果，帮助理解内存占用情况。
std::cout << "char:" << sizeof(char) << std::endl;
std::cout << "short:" << sizeof(short) << std::endl;
std::cout << "int:" << sizeof(int) << std::endl;
std::cout << "long:" << sizeof(long) << std::endl;
std::cout << "float:" << sizeof(float) << std::endl;
std::cout << "double:" << sizeof(double) << std::endl;
std::cout << "uchar:" << sizeof(uchar) << std::endl;
char:1
short:2
int:4
long:8
float:4
double:8
uchar:1
