C Variables 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 and Answers
1. What will be the output of the C program?
#include<stdio.h>
int main()
{
int 1_one = 25;
printf("%d",1_one);
return 0;
}
x
Option: D
Explanation
Invalid variable name. Variable name must begins with either alphabet or underscore( _ ).
2. What will be the output of the C program?

int main(){
int default = 5, a = 3;
if(a > 2)
printf("%d",default);

Though int is a keyword, it is prefixed with underscore, this makes it possible to use _int as a variable.
