Pointers Questions and Answers
Pointers questions with answers are a crucial part of C programming preparation, often included in technical interviews and MCQ-based exams. Pointers are variables that store the memory address of other variables, making them fundamental to dynamic memory management and efficient program design. These C programming MCQ questions and answers help students understand pointer arithmetic, function pointers, arrays, and memory allocation. Commonly asked in placement exams by TCS, Infosys, and Wipro, mastering pointer concepts gives you a competitive edge in coding tests and programming interviews.

211. Which of the following statement agree weith the statement "It declares a function that recives a pointer to a pointer to a char and returns a pointer to a pointer to a pointer to a char"
- char *MyFun (char **);
- char **Myfun (char **);
- char ***Myfun(char**);
- None of these
212. What is the true about the code static char vo1atile const *Myfun( ) { static char vo1atile const *p="Madhu"; return p; } void main ( ) { printf("%s",MyFun( ) ); }
- The code is perfect and output is Madhu
- Error too many storage class
- No error but p is a dangling pointer
- Error leading to memory curruption.
213. Find the output void main ( ) { const int i=5; const int *p; int *q; p=&i; q=&i; (*q)++; printf("\n %d, %d\n", *p, *q); }
- 6, 5
- 5, 6
- 6, 6
- Compilation error
214. Find the output void main ( ) { int a[ ] [3] = {a, 2, 3, 4, 5, 6}; int (*ptr)[3]=a; printf ("%d %d",(*ptr) [1], (*ptr)[2]); ++ptr; printf("%d %d",(*ptr)[1], (*ptr) [2]); }
- 2 3 5 6
- 2 3 4 5
- 4 5 0 0
- None of the above
215. Which format specifier is used to find out the offset address of a variable ?
- %o
- %p
- %h
216. Find the output void main ( ) { int *p=(int*) f( ); *p=9; printf("%d", *p); } f() { int *p=malloc(2*sizeof(int)); return p; }
- 9
- 4
- compilation error
- None of these
217. Find the output void main () { char huge *p=(char huge*) 0x02220110; char huge *q=(char huge*)0x00002330; if (p==q) printf("equal and Normalized"); else printf("Not Equal and NOrmalized"); }
- Nor equal and normalized
- Equal and normalized
- Memory scratch
- Huge pointers can't be compared
