Free function question

I was practicing free function and I wrote this piece of code #include <stdio.h> #include <stdlib.h> int main() { int *ptr; ptr = malloc(10*sizeof(*ptr)); /* a block of 10 ints */ if (ptr != NULL) *(ptr+2) = 50; /* assign 50 to third int */ printf("%d\n", *(ptr+2)); /* 50 */ free(ptr); printf("%d\n", *(ptr+2)); return 0; } I expected the output to come as 50 (and a random number) but the output screen showed "No output." Can anyone explain how the code is running?

Your code is working. The problem is the Sololearn server. Sometimes it doesn't respond that's why it only shows 'No output'. Just try it a few more times.
