Answer:
error: incompatible types
Explanation:
Given
The attached code
Required
The output
Variable "a" is declared as float
While p is declared as a pointer to an integer variable
An error of incompatible types will be returned on line 3, <em>int *p = a;</em>
Because the variables are not the same.
To assign a to p*, we have to use type casting.
Hence, (b) is correct
Hey hey hey! I recently took the test and the answer is D | (• ◡•)|
Answer:
The solution code is written in C++
- float cellPhone(int m, int tx){
- float COST_PER_MIN = 0.1;
- float COST_PER_MESSAGE = 0.2;
-
- float bill_amount = m * COST_PER_MIN + tx * COST_PER_MESSAGE;
-
- return bill_amount;
- }
Explanation:
Firstly, declare a function named cellPhone() that takes two input parameters, m and tx (Line 1).
Since the policy of the carrier company is not given in the question, I make a presumption that the cost per minutes is $0.10 and the cost per message is $0.20 (Line 2- 3).
Next, apply the formula m * COST_PER_MIN + tx * COST_PER_MESSAGE to calculate the total bill (Line 5) and return the bill_amount as function output (Line 7).
