C Data Types Tricky Questions
In most of the MNC interview questions such as in ZOHO interview question, IVTL Infoview interview questions, Amazon interview questions, GOOGLE interview questions, Infosys interview questions and even in Voonik interview questions, We come across several Tricky C Questions about which 2:5 of the questions are from data types in c. Solving that kind of tricky C questions is not an easy task for all C programmers. We need more practices to solve it with ease. So we provide 25+ interesting C questions in data types to make your MNC interview very easy.
Data Types Tricky Questions and Answers
6. Which of the following data type is right in C programming?
x
Option: D
Explanation
Sorry, no explanation.
7. Which one of the following is incorrect?
A. enum fruits = { apple, banana }f;✔
B. enum fruits{ apple, banana }f ;✘
C. enum fruits{ apple, banana };✘
x
Option: A
Explanation
Syntax error occur in option A.
8. What will be the output of the C program?
#include<stdio.h>
int main(){
float me = 5.25;
double you = 5.25;
if(me == you)
printf("I love U");
else
printf("I hate U");
return 0;
}
x
Option: D
Explanation
For floating point numbers (float, double, long double) the values cannot be predicted exactly. Depending on the number of bytes, the precession with of the value represented varies. Float takes 4 bytes and long double takes 10 bytes. So float stores 0.9 with less precision than long double.
9. What will be the output of the C program?
#include<stdio.h>
int main()
{
extern int num;
num = 5;
printf("%d", num);
return 0;
}
x
Option: B
Explanation
extern is a C keyword which specifies to the compiler that the memory for num is allocated in some other program and that address will be give to our current(this) program at the time of execution or linking. Here extern int num; is declared within the scope of the program.
10. What will be the output of the C program ?
#include<stdio.h>
int main(){
char *ptr;
printf("%d %d", sizeof(*ptr), sizeof(ptr));
return 0;
}
x
Option: C
Explanation
The sizeof() operator returns the number of bytes taken by its operand ptr.Here *ptr is the character pointer which holds the memory byte of 1 and ptr is allocated with 4 bytes to hold the address of the character pointer variable *ptr
