Previous Year Question (PYQs)
What is the output of the following program ?
#include <iostream>
using namespace std;
struct demo
{
int var;
};
int main()
{
demo str;
demo *ptr;
str.var = 100;
ptr = &str;
cout << ptr->var;
return 0;
}
Solution
Output:
100
Explanation:
str.var = 100; assigns 100 to the structure variable.
ptr = &str; makes the pointer point to str.
ptr->var accesses the member var of structure str via pointer.
Hence it prints 100.
