Evaluate the following and choose the correct answer.
a/b+c*d where a=4, b=2, c=2, d=1.
a) 1
b) 4
c) 5
d) 2
Explanation: * and / have higher priority. Hence, they are evaluated first. Then, + is evaluated. Hence, 2+2=4.
Evaluate the following statement using infix evaluation algorithm and choose the correct answer. 4*2+3-5/5
a) 10
b) 11
c) 16
d) 12
Using the evaluation of infix expression, evaluate a^b+c and choose the correct answer. (a=2, b=2, c=2)
a) 12
b) 8
c) 10
d) 6
Explanation: ^ has the highest precedence. Hence, 2^2 is evaluated and then 4+2 gives 6.
Evaluate the following infix expression using algorithm and choose the correct answer. a+b*c-d/e^f where a=1, b=2, c=3, d=4, e=2, f=2.
a) 6
b) 8
c) 9
d) 7
