Answer 1

Answer-

A)-

• int X;
• X = 10;
• cout << x << endl;

Error — yes!

• In this statement cout << x << endl; here X is used in small letter.

B)-

• char gpaValue;
• cin>>gpaValue;

Error — None !

• It is asking to enter data but it not prints the data.

C)-

• float num1, num2, num3;
• cin>>num1>>num2>>num3;  
• float average = num1 + num2 + num3 / 3;

Error — None !

• It is asking to enter data but it not prints the data. If you want to print average then use cout <<  average;
