C Variables Interview 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 Variables 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 Variables to make your MNC interview very easy.
C Variables Questions
11. What will be the output of the C program?
#include<stdio.h>
int main()
{
int scanf = 13;
printf("%d",scanf);
return 0;
}
x
Option: B
Explanation
scanf as a variable name is possible because we have not used it as function declaration( int scanf()=13 ).
12. What will be the output of the C program?
#include<stdio.h>
int main()
{
int printf = 13;
int c = 7 + printf;
printf("%d",c);
return 0;
}
x
Option: A
Explanation
What's wrong with printf here and what's right with previous question scanf. Here we explain
printf can be declared as a variable, when to outputted the value stored in the printf variable, we use printf() inbuilt function.
when we use printf() it will search for printf() function in our program, here we declared printf as a variable and not as a function , thus it leads to compiletime error.
13. What will be the output of the C program?
#include<stdio.h>
int main()
{
char printf[25] = "printf";
puts(printf);
return 0;
}
x
Option: D
Explanation
As we explained in previous program, we used puts() instead of printf() in-built function. Thus there is no problem with output.
14. What will be the output of the C program?
#include<stdio.h>
int main(){
int EOF = 0;
printf("%d",EOF);
return 0;
}
x
Option: B
Explanation
In C, EOF is a predefined macro constant. We do not have any permission even to declare EOF as a variable name. Then for sure we cannot declare or increment any values to EOF- End Of File
15. What will be the output of the C program?
#include<stdio.h>
int main(){
int VARIABLE = 15;
printf("%d",variable);
return 0;
}
x
Option: C
Explanation
C is case-sensitive as all common programming language.
