1. (20 points) What types of error is each of the following? *Forgot to add a ; when declaring a variable *When computing the area of a circle, you used the formula: area = 2 * PI * radius.

2. (25 points) What happens when the statement below executes and the values -3, A, and 4.5 are entered?

int x; char y; double z; scanf("%d%c%f", &x, &y, &z);

3. (30 points) What is the output of the following code segment when the user enters the values: -13, C, and 12.45678 in order.

#include int x; char y; double z; printf("Enter an integer, a character, and a number with digits after

decimal point: "); scanf ("%d%c%f", &x, &y, &z); x = x + 3; y = y - 1; z = x * z; printf(" x = %6d", x); printf(" y = %5c", y); printf( z = %8.3f", z); printf( Stop.);

3. (25points be precise and use correct terminology) a. (a one word answer will do for this question) What kind of a C language statement is

int x;

b. What is the effect of this statement? (What does the compiler do with this statement?)

c. What would happen during the compilation of your program if this statement were omitted from this code and the compiler later encountered the statement x = x + 3; ?
