When the program below is compiled and executed, it produces the
following output:
min value is -./,),(-*,(
max value is 2147483647
When the two lines containing cout are commented out and the printf
line is uncommented, the following output is produced:
e is -2147483648, f is 2147483647
------------------------------------------------------------------------
#include <stream.h>
main()
{
int e;
int f;
e = 1;
/* make larger */
while (e > 0)
{
e <<= 1;
f = e - 1;
}
cout << "min value is " << (int)e << '\n';
cout << "max value is " << (int)f << '\n';
/* printf("e is %d, f is %d\n", e, f); */
}
