Matric Number:
2. Let
x be the first three digits of your matric number, AND
y be the last three digits of your matric number. If the first digit of y is 0, replace it with
2.
Ехатple:
If you matric number is 2013034,
Thus, x = 201 and y = 234
a. Write the values of x and y based on your matric number.
b. If a = x (mod 7) and b = (-1) + y (mod 7), find the integer(s) c with 10
is an operator which can be used for checking if two values are the same.
C Language - Given a highway number, indicate whether it is a primary or auxiliary highway. If auxiliary, indicate what primary highway it serves. Also indicate if the (primary) highway runs north/south or east/west.
