Question

How many times will an "X" appear in the following nested loop?
for (outer = 0; outer <=5; outer++)
{for (inner = 1; inner <=4; inner+1)
{cout<<("X");}
}

9
	10
	20
	24
	none of the above

Answer 1

answer option D

we can see that in the post condition of the inner loop it is mentioned just inner+1

so it is like

inner +1 ;

so the value of inner is always 1 and leads to infinite loop

#include <bits/stdc++.h>

using namespace std;

int main()

{

    int outer, inner;

    for (outer = 0; outer <= 5; outer++)

    {

        for (inner = 1; inner <= 4; inner + 1)

        {

            cout << "The value of inner is " << inner << endl;

            cout << ("X");

        }

    }

    return 0;

}
