で調べることができる。

code:cpp

using namespace std;

int main()

{

cout << "sizeof(char) = " << sizeof(char) <<< endl;

cout << "sizeof(short) = " << sizeof(short) << endl;

cout << "sizeof(int) = " << sizeof(int) << endl;

cout << "sizeof(long) = " << sizeof(long) << endl;

cout << "sizeof(float) = " << sizeof(float) << endl;

cout << "sizeof(double) = " << sizeof(double) << endl;

cout << "sizeof(long double) = " << sizeof(long double) << endl;

}
