C++: what is i and j. IMPORTANT I know it's 3 and 3 but can someone please explain how we can get to that conclusion by just reading the code, can it be explained to me because when i try to do it I get a different answer for i and j I got 1 and 4.
#include <iostream>
using namespace std;
int main()
{
int i = 1;
int j = 0;
if (i++ == 1)
{
j = ++ i;
}
else
{
j+=4;
}
cout << i<< " and " << j <<endl;
return 0;
}
Homework Answers
i=1 and j=0
if(i++ ==1 ) i++ is post increment so here i is taken as 1 so 1==1
true,
now i++ so i=2 and j=0
j=++i so here ++i is pre increment so 1st it will increment so
i=3
so j=3
Note : Please comment below if you have concerns. I am here to help
you
If you like my answer please rate and help me it is very Imp for
me

In addition to including an exceptions library, you can also create exceptions by using the throw keyword. (1pt) Create a function called int throwsInt() that will throw an integer (1pt) Create a function called double throwsDouble() that will throw a double (2pt) Using try/catch statements, expand the code stubs to call each function in it's own try block, and catch and report the thrown value. Provided code: #include <iostream> using namespace std; int throwsInt(); double throwsDouble(); int main() { cout...
