Reporters and city officials gathered at a Chicago railroad station one afternoon in 1953. The person they were meeting was the 1952 Nobel Peace Prize winner. A few minutes after the train came to a stop, a giant of a man - six feet four inches - with bushy hair and a large moustache stepped out from the train. Cameras flashed. City officials approached him with hands outstretched. Various people began telling him how honoured they were to meet him.

The man politely thanked them and then, looking over their heads, asked if he could be excused for a moment. He quickly walked through the crowd until he reached the side of an elderly black woman who was struggling with two large suitcases. He picked up the bags with a smile, escorted the woman to a bus. After helping her aboard, he wished her a safe journey. As he returned to the greeting party he apologized, "Sorry to have kept you waiting." Not many whites would have done what he did.

The man was Dr. Albert Schweitzer, the famous missionary doctor who had spent his life helping the poor in Africa.

Q:

Point out the error, if any, in the following program.

main()

{

    int ( *p )() = fun;

    ( *P ) ();

}

fun ()

{

    Printf ( "\nLoud and clear" );

Answer

Here we are initalising the function pointer p to the address of the function fun(). But during this initialisation the function has not been defined. Hence an error.


To eliminate this error add the prototype of the fun() before declaration of p, as shown below:


extern int fun();    or simply  int fun();
