What will be the output of the program ?
#include <stdio.h>
#include <string.h>
int main()
{
int i, n;
char *x="Alice";
n = strlen(x);
*x = x[n];
for(i=0; i<=n; i++)
{
printf("%s ", x);
x++;
}
printf("\n", x);
return 0;
}
Answer: D
Correct answer: lice ice ce e
x[n] is the terminating null, and *x = x[n] writes it over the first character, so the string becomes an empty string followed by lice.
The first iteration therefore prints nothing before its space. Each subsequent iteration advances x by one and prints the remaining tail - lice, ice, ce, e. Note that x points to a string literal, so writing through it is undefined behaviour and would fault on many modern systems.
