Assignment #3
Problem #1
Same problem as we did in class. Below is the mystery program. Its output is listed in the header of the program.
/* mystery.cpp
// D. T.
// mystery program
// To compile and run this program:
//
// g++ mystery.cpp
// a.out
//
// The output of the program is the following
//
// 27001
// -31534
//
// With what positive values were x and y initialized
// at the beginning of the program. Explain why.
// (a short int contains 16 bits)
*/
#include <stdio.h>
main() {
short int x = ?????;
short int y = ?????;
x = x+y;
printf( "%d\n", x );
x = x+y;
printf( "%d\n", x );
}
What two positive numbers are stored in x and y to create the output listed in the header?
Explain your answer.
