Question

C programing -

can you check my work?

Given the following variable declarations complete the table below. Assume the proper header files have been included. char a, b, C; int d,e - 20. f = 16 : int *p = NULL, , **q = NULL, *r = NULL; double g, h, i; double *s = NULL , *t = NULL , *u = NULL; Expression For each expression list what the variable declaration would look like. Data Type C Declaration Syntax char INT pointer to an. &p Pouter to Pointer on to a a dable dochle For each statement circle whether there is a type mismatch or there is no type mismatch. Statement a = b; *p = e; p = &f ; *p = &d; q = &p; t = 0; S = 9; Data Type Type Mismatch? Type Mismatch / No Type Mismatch Type Mismatch 1 No Type Mismatch Type Mismatch No Type Mismatch Type Mismatch ! No Type Mismatch Type Mismatch _ ! No Type Mismatch Type Mismatch No Type Mismatch Type Mismatch ! No Type Mismatch .

Answer 1

Question 1:

Answer:

Expression Data Type C Declaration Syntax Correct char I INT Pointer Correct to an int. Correct pa &p Address of pointer variable a Donter to Pointer into d able Address of double type variable dochle a Correct

Question 2:

Answer:

Statement a = b ; *p = e; p = &f ; *p = &d; q = &p; t = ; s = 9; Data Type Type Mismatch? Type Mismatch / No Type Mismatch Correct Type Mismatch 1 No Type Mismatch Correct Type Mismatch ! No Type MismatchIncorrect Type Mismatch / No Type Mismatch Correct Type Mismatch ! No Type MismatchCorrect Type Mismatch / No Type MismatchCorrect Type Mismatch ! No Type MismatchIncorrect

The statement as given below:

*p = e;

There is not type mismatch but pointer 'p' is pointing to the NULL location. So, this statement will result in a Segmentation fault (core dumped)

The statement as given below:

*p = &d;

It will display the warning message because we are trying to make the assignment of an integer from pointer without casting.

The statement as given below:

s = g;

The 'g' is a double type variable but 's' is a pointer to double type. So, this statement will result in an error message.
