C Variables 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 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
6. What will be the output of the C program?
#include<stdio.h>
static num=5;
extern int num;
int main()
{
printf("%d",num);
return 0;
}
x
Option: D
Explanation
Two of the global variable can have same variable name.
7. What will be the output of the C program?
#include<stdio.h>
static num=5;
extern int num=10;
int main()
{
printf("%d",num);
return 0;
}
x
Option: A
Explanation
Though global variables can have same name, but we can initialize only one of them.
8. What will be the output of the C program?
#include<stdio.h>
int main()
{
int min-value = 2;
int max-value = 10;
int avg = max-value + min-value / 2;
printf("%d",avg);
return 0;
}
x
Option: D
Explanation
Special characters are not allowed in declaring a variable name. In this case the special character is min-value.
9. What will be the output of the C program?
#include<stdio.h>
int main(){
struct num
{
int num;
};
struct num key={25};
printf("%d",key.num);
return 0;
}
x
Option: B
Explanation
Two variables(num) can have same name in different scope.
10. What will be the output of the C program?
#include<stdio.h>
int main()
{
printf("%d",EOF);
return 0;
}
x
Option: C
Explanation
In C, EOF - End of File which is a macro and its header file is stdio.h. In C, EOF is equal to -1 by default. We can use EOF in some programs to check whether file pointer reaches the end of the file.
