Searching for "i"

Q:

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

main()

{

    int i = 4, j = 2;

    switch(i)

    {

     case 1 :

       printf (''\n To err is human, to forgive is against company policy.");

        break;

      case j :

       printf (''\n if you have nothing to do, don't do it here.");

       break;

    }

}

Answer

Constant expression required in the second case, we cannot use j.

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();

Q:

What would be the output of the following program?

main()

{

    extern int fun ( float );

    int a;

    a = fun ( 3. 14 );

    printf ("%d", a);

}

int fun ( aa )

float aa ;

{

     return ( (int) aa );

}

Answer

Error occurs because we have mixed the ANSI prototype with K & R style of function definition.


When we use ANSI prototype for a function and pass a float to the function it is promoted to a double. When the function accepts this double into a float a type mismatch occurs hence the error.


The remedy for this error could be to define the function as :


int fun (float aa)


{


  ....


}

Q:

What is the difference between the following declarations?

extern int fun();

int fun();

Answer

There is no difference except for the fact that the first one gives a hint that the function fun() is probably in another source file.

Answer

extern int i is a declaration and not a definition, hence Error occured.

Q:

What is Line of credit?

Answer

Line of credit is an agreement or arrangement between the bank and a borrower, to provide a certain amount of loans on borrower’s demand. The borrower can withdraw the amount at any moment of time and pay the interest only on the amount withdrawn. For example, if you have $5000 line of credit, you can withdraw the full amount or any amount less than $5000 (say $2000) and only pay the interest for the amount withdrawn (in this case $2000).
