LAB ACTIVITY 5: Arithmatic Expression and Operators

a. Convert these mathematical expression into C expression

1.  y = m*x +c
2. (2*a) / b * 3 *c
3. 9*p + 2*q ( r + 2 ) / 2*(s -1)
4. ( (3*e - d) / (x - 9) ) - ( (4 - pow (c,3)) / 4*y )

b. Determine the order of solving the expressions below and calculate the value of x.

1. x = 15
2. x = 3
3. x = 108
4. x = 1

c. Given the value of num1=26. Determine the value of num2 after the execution for each of
the following statement.

1.  24
2.  26
3.  24
4. 27

d. Assume i, j and k are integer variables with i=3 and j=4. Determine the value of k for

each of the following statement. (Assume that each of the operation is non-contiguous)

1. k = j++;
      = 4
2. k = ++j;
      = 5
3. k = ++i * j--;
      = 5*4
      = 20
4. k = j++ * --i;
      = 4*2
      = 8
5. k = j * i/j--;
      = 4* 3/4
      = 3
6. k = 24/j++ - 16 % i;
      = 24/4 - 16 % 3
      = 6 - 1
      = 5

e.   Determine the output of the program below

  

      Output :

      1: 10
      2: 10
      3: 11

      4: 11

      5: 11

      6: 31
      7: -11

      8: 32

      9: 32

    10: 32

    11: 0

    12: 1
    13: 0
