ENGG1340 Computer Programming II Module 3 Self-Review Exercise
1. Evaluate the following expressions:
a) 36 / 5
b) 18 − 32 / 6 * 3
c) 6 − 8 % 11
d) 22.0 / 5
e) 25 − 7 % 3 + 8 / 3
f) 18.0 + 5.0 * 3.0 / 4.0
2. Suppose x, y, and z are int variables and x = 2, y = 5, and z = 6. What is the output of each of the following statements?
a) cout << "x = " << x << ", y = " << y << ", z = " << z;
b) cout << "Sum of " << x << " and " << z << " is " << x + z;
c) cout << "2 times " << x << " = " << 2 * x;
3. The following program has syntax mistakes. Correct them. On each successive line, assume that any preceding error has been corrected.
const char = STAR = '*' const int PRIME = 71; int main {
int count, sum; double x; count = 1; sum = count + PRIME; x := 25.67; newNum = count * ONE + 2; sum + count = sum; x = x + sum * COUNT;
cout << " count = " << count << ", sum = " << sum
<< ", PRIME = " << Prime << endl;
}
4. Suppose a, b, and c are int variables and a = 5 and b = 6. What value is assigned to each variable after each statement executes? If a variable is undefined at a particular statement, report UND (undefined).
a
b
c
a = (b++) + 3;
c = 2 * a + (++b);
b = 2 * (++c) - (a++);
