post sample code in two versions: for loop and while loop. Add one line comment to explain what the code is doing. Code using for loops (and while) is a great place to practice compound assignments. Here is an example: // factorial of n -- assuming all vars are declared int, n has been input and is >=0 tot=1 for (int i=n; i>0; i--){ tot*=i; } printf(factorial of %d is %d , n,tot); // using while i=n; tot=1 while (i >0) { tot*=i; i--; } printf(factorial of %d is %d , n,tot); // there's one difference between the two codes; what is it?
