NAME:


Note: total of 20 points for the paper part, and 20 points for the computer
part - for a grand total of 40 points.

Grading: 
(1) and (2) worth 12 points.  8 points if you get one of them 
exactly correct and don't even answer the other.  For each one, 1/2 the
points for the final printed values, and 1/2 for showing the values of 
variables, and which functions.
(3) and (4) worth 8 points, 5 points for (3) and 3 points for (4).





(1) "Be the computer".  Keep track of the values of variables, which
    functions are running, and what is printed as the following executes.  

// usual #include stuff...

int main(int argc, char *argv[]) {
    int i;
    int total = 0;
    for(i=0; i < 30; i = i + 5) {
        printf("%d\n", i);
	total = total + i;
    }
    printf("%d\n", total);

    return 0;
}





































(2) "Be the computer".

// usual #include stuff...

void something(int nums[], int howMany) {
     int i;
     for(i=0; i < howMany; i++) 
         printf("%d", nums[i]);
     printf("\n");
}

int main(int argc, char *argv[]) {
    int numbers[5] = {5, 6, 7};
    int j;
    
    for(j=1; j <= 3; j++)
        something(numbers, j);

    return 0;
}















(3) Short Answer.  List and explain the 4 main parts of a for loop.




















(4) Short Answer.  Explain the differences and similarities between a 
    while loop and an if statement.
