- A vital component of any database engine is the Data dictionary.
Other options are incorrect because they are not follow the given scenario.
Answer:
See explanation
Explanation:
Given
The above program that subtracts two numbers and returns the result
Required
Modify the source code to run perfectly
When the given program is tested, it displays
<em>4 minus 10 equals -6
</em>
<em></em>
<em>Which is different from the expected output of</em>
<em>10 minus 4 equals 6
</em>
<em></em>
Modify
<em>solution = minuend-subtrahend
</em>
<em>to</em>
<em>solution = subtrahend - minuend</em>
<em></em>
And that does it.
High-level language programs must be translated into machine language before they can be executed. (Machine language instructions are encoded as binary numbers that are meant to be used by a machine, not read or written by people. The Java compiler translates Java programs into a language called Java bytecode.
Answer:
The function definition to this question can be given as:
Function definition:
void printAttitude(int x1) //define function printAttitude.
{
//nested else-if statements
if(x1==1)
//if block
cout<<"disagree"<<endl;
//message
else if(x1==2)
//else if block
cout<<"no opinion"<<endl;
//message
else if(x1==3)
//else if block
cout<<"agree"<<endl;
//message
else
cout<<" ";
}
Explanation:
In the above method definition firstly, we define a method that is "printAttitude". In this method, we pass an integer variable that is "x1". This function does not return any value because its return type is void. In this method, we use nested else-if statements. The description of these conditions can be given as:
- In the if block we check the variable x1 value is equal to 1 If this condition is true. It will print "disagree" otherwise it will go to else-if block.
- In the else-if block, we check the variable x1 value is equal to 2 if the condition is true. It will print "no opinion". otherwise, we will go to another else-if block.
- In this block, we check the variable x1 value is equal to 3 if this condition is true. It will print "agree".otherwise it will go to else block.
- In the else block it will print nothing.
