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
