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.
