Now let us see how to use printf() and different format specifiers for additional arguments of different data types in a single printf() and scanf() functions. 2 variables are declared of different types; integer “a” and float “b”. In the next line, a text is displayed through the ...

You've committed and reserved all of the memory in the first call. If you want to use VirtualAlloc to set aside memory and retrieve it by pages, your first call should only do a MEM_RESERVE on the maximum size of memory you plan to use. Then when you need more, you will make ...
scanf("%d",&num); printf("Factorial of %d is %d", num, factorial(num)); return0; } The above code prompts the user to enter a non-negative integer and calculates its factorial using a recursive function calledfactorial(). The function first checks if the base case is met (i.e., ...
