C Interview Data Types 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.
Interview Data Types Questions
21. What will be the output of the C program?
#include<stdio.h>
int main()
{
char *ptr = "c-aptitude%s";
printf(ptr);

typedef int num;
num num1 = 5;
printf("%d", num1);
return 0;
}
x
Option: C
Explanation
Here the program creates a user defined type num and creates a variable num1 of type num. Hence there is no problem with the output
