Expert Solution & Answer
Chapter 4, Problem 10CP
Explanation of Solution
Given: The following code:
#include
using namespace std;
int main()
{
char x = 'a';
char y = 'c';
cout << ++x << endl;
cout << y++ << endl;
cout << (x - y) << endl;
return 0;
}
To find: The output of the following code.
#include
using namespace std;
int main()
{
char x = 'a';
char y = 'c';
cout << ++x << endl;
cout << y++ << endl;
cout << (x - y) << endl;
return 0;
}Â
Solution:
In the above program, the ASCII values and character codes of the variables are printed accordingly. Along with that the pre increment and post increment operations are performed as well in the variables, x and y, respectively...
