Storage Classes Interview Q&A
1.We can insert pre written code in a C program by using
- #read
- #get
- #include
- #put
2. The first expression in a for loop is
- Step value of loop
- Value of the counter variable
- Any of above
- None of above
3. Break statement is used for
- Quit a program
- Quit the current iteration
- Both of above
- None of above
4. Continue statement used for
- To continue to the next line of code
- To stop the current iteration and begin the next iteration from the beginning
- To handle run time error
- None of above
5. What will be output of
#include
void main()
{
char test =`S`;
printf("\n%c",test);
}
- S
- Error
- Garbage value
- None of above
6. Due to variables scope in c
- Variables created in a function cannot be used another function
- Variables created in a function can be used in another function
- Variables created in a function can only be used in the main function
- None of above
7. What will be the output of following program
#include
main()
{
int x,y = 10;
x = y * NULL;
printf(\"%d\",x);
}
- error
- 0
- 10
- Garbage value
8. Difference between calloc() and malloc()
- calloc() takes a single argument while malloc() needs two arguments
- malloc() takes a single argument while calloc() needs two arguments
- malloc() initializes the Allocated Memory to ZERO
- calloc() initializes the allocated memory to NULL
9. Exit() is same as return
- TRUE
- FALSE
10. calloc() belongs to which library
11. If include files can be nested
12. Which of the following below is/are valid C keywords
- stdlib.h
- malloc.h
- calloc.h
- None of above
11. If include files can be nested
- Yes
- No
12. Which of the following below is/are valid C keywords
