Answer:
public class Calculator {
private int total;
private int value;
public Calculator(int startingValue){
// no need to create a new total variable here, we need to set to the our instance total variable
total = startingValue;
value = 0;
}
public int add(int value){
//same here, no need to create a new total variable. We need to add the value to the instance total variable
total = total + value;
return total;
}
/**
* Adds the instance variable value to the total
*/
public int add(){
// no need to create a new total variable. We need to add the value to the instance total variable
total += value;
return total;
}
public int multiple(int value){
// no need to create a new total variable. We need to multiply the instance total variable by value.
total *= value;
return total;
}
//We need to specify which value refers to which variable. Otherwise, there will be confusion. Since you declare the parameter as value, you need to put this keyword before the instance variable so that it will be distinguishable by the compiler.
public void setValue(int value){
this.value = value;
}
public int getValue(){
return value;
}
}
Explanation:
I fixed the errors. You may see them as comments in the code
<u>B. Microphone</u> helps Carol to use the speech recognition software.
<u>Explanation</u>:
A microphone is a hardware device which converts the sound waves in the air into electronic signals. The electrical signals are transferred to a recording medium. Four main types of microphones are as follows:
i) Cardioid
ii) Super cardioid
iii) Omni
iv) Figure 8
Handheld microphone can be used better with the home theater or a karaoke machine. The speech recognition software can be used with the help of microphone. Cabling problem can be avoided with the use of microphone, thus cable trip hazard can also be avoided.
I have this same problem but I’m a senior.
Answer:
Compiler.
Explanation:
Actually there are two things missing in the code first is the header file.There is only # include no filename is there like<iostream>,,bits/stdc++.h> etc.cin ,cout will not work until iostream is included in the program.After including the header properly the missing semicolon will be caught by the compiler.The error will be as following:-
expected ';' before return.
