Question

Which is a legal call to the function? "myTotal" is an integer variable.

void report(int total);

a)report( );

b)report(myTotal);

c)int report(myTotal);

d)report(int myTotal);

Answer 1

Correct Answer

b) report(myTotal);

Reason

The function call must match the syntax of the programming language.

That is - function_name(arguments);

Explanation

The function call must include the name of a function and an argument according to its prototype.

In this case, the prototype is -

void report(int total);

Hence the function should be in a format, without any data types included.

The correct answer is - report(myTotal);

Rest of them are wrong (as explained below) -

a)report( ); - no argument passed

c)int report(myTotal); - int keyword is not required

d)report(int myTotal); - int keyword is not required
