第二个C++程序，认识各种数据格式

#include<iostream>#include<climits>int main(){using namespace std;int n_int=INT_MAX;short n_short=SHRT_MAX;long n_long=LONG_MAX;long long n_llong=LLONG_MAX;cout <<"int is "<<sizeof(int)<<"bytes."<<endl;cout <<"short is "<<sizeof n_short<<"bytes."<<endl;cout <<"long is "<<sizeof n_long<<"bytes."<<endl;cout <<"long long is "<<sizeof n_llong<<"bytes."<<endl<<endl;cout<<"Maximum values:"<<endl;cout<<"int:"<<n_int<<endl;cout<<"short: "<<n_short<<endl;cout<<"long: "<<n_long<<endl;cout<<"long long: "<<n_llong<<endl<<endl;cout<<"Minimum int value="<<INT_MIN<<endl;cout<<"Bits per byte= "<<CHAR_BIT<<endl;return 0;}
