Predict the output of below program
#include<stdio.h>
int main()
{
char *ptr = "geeksforgeeks";
printf("%c\n", *&*&*ptr);
getchar();
return 0;
}
Output: g
Explanation: The operator * is used for dereferencing and the operator & is used to get the address. These operators cancel effect of each other when used one after another. We can apply them alternatively any no. of times. For example *ptr gives us g, &*ptr gives address of g, *&*ptr again g, &*&*ptr address of g, and finally *&*&*ptr gives ‘g’
Now try below
#include<stdio.h>
int main()
{
char *ptr = "geeksforgeeks";
printf("%s\n", *&*&ptr);
getchar();
return 0;
}
