    D. none of the above.

   

69. The following function prototypes

        int increment(char);

Answer 1

61. The following program is accepted by the compiler:

int sum( int x, int y )

{

int result;

result = x + y;   

}   

False, because the method has a return type integer but the method in its defination does not return anything.

62. The following implementation is accepted by the compiler:

void product()

{

int a; int b; int c; int result;

cout << "Enter three integers: ";

cin >> a >> b >> c;

result = a * b * c;

cout << "Result is " << result;

return result;

}

  

False, because the return type is void and we are returning an integer from the function

63. The following program has no error:

using namespace std;

int main()

{

double number1, number2, sum;

cout << "Enter a number: ";

cin >> number1;

cout << "Enter another number: ";

cin >> number2;

sum = number1 + number2;

cout << "The sum of the two numbers is " << sum;

return 0;   

}

True, the program runs without error

64. The following program is syntactically incorrect:

#include <iostream>

using namespace std;

int main()

{

const number1, number2, product;   

  

cout << "Enter two numbers and I will multiply\n";

cout << "them for you.\n";

cin >> number1 >> number2;

product = number1 * number2;   

cout << product;

}

False, as we have not provided a data type to the variables number1,number2,product.

65. The following program is syntactically correct:

#include <iostream>

using namespace std;

int main()

{

double number1, number2, sum;

cout << "Enter a number: ";

cin >> number1;

cout << "Enter another number: ";

cin >> number2;

number1 + number2 = sum;   

cout << "The sum of the two numbers is " << sum;

return 0;

}

False, as expression can be assigned to a variable, a variable can never be assigned to an expression

66. The following is a function prototype:

CalcTotal();

False, it should have a return type.   

67. Parameter names in a prototype are optional.

true, you can have or not have parameters in a function

68. Overloaded functions:

A. are a group of functions with the same name and same

number of arguments.

B. are a group of functions with the same name and

different parameter types.

C. make life easier for the programmer.

D. none of the above.

Overloaded functions are the one with same names but different parameter types.

69. The following function prototypes

int increment(char);

int increment(int);

are not accepted in C++ because they have the same name.

False, they are accepted as they are overloaded functions with different data types.

70. The following function prototypes are not accepted by compiler:

int GetValue();   

double GetValue();

True, as functions overloaded with different return types are not accepted.
