What is the output of the program
#include<stdio.h>
int main()
{
struct emp
{
char name[20];
int age;
float sal;
};
struct emp e = {"Tiger"};
printf("%d, %f\n", e.age, e.sal);
return 0;
}
Answer: Option
Explanation:
When an automatic structure is partially initialized remaining elements are initialized to 0(zero).

If anyone please explain the below concept, I can' t understand that:
If we use: printf("%s %d, %f\n", e.name, e.age, e.sal);
struct emp e = {"Tiger", 5, 1500.50}; // Full Initialization.
//Ouput: Tiger, 25, 1500.500000.
struct emp e = {"Tiger"}; // Partial Initialization.
//Ouput: Tiger, 0, 0.000000.
struct emp e ; // No Initialization.
//Ouput: GarbageValue, GarbageValue, GarbageValue!
If we use: printf("%s %d, %f\n", e.name, e.age, e.sal);
struct emp e = {"Tiger", 5, 1500.50}; // Full Initialization.
//Ouput: Tiger, 25, 1500.500000.
struct emp e = {"Tiger"}; // Partial Initialization.
//Ouput: Tiger, 0, 0.000000.
struct emp e ; // No Initialization.
//Ouput: GarbageValue, GarbageValue, GarbageValue!

I hope this help you. Have a nice day

#include<stdio.h>
int main()
{
struct emp
{
char name[20];
int age;
float sal;
};
struct emp e = {" ",24,67888};
printf("%d, %f\n", e.name, e.sal);
return 0;
}
Output is :-1086310732, 67888.000000
Why name is in -ve, it should also be 0.

String contains null character in it i.e "\0" is same as " ".
String takes the memory, it has given the address value of the null character stored.
For example if you have "tiger" which also have null character in it. i.e "tiger\0"
Any string at the end contains null.

Sundar ji your explation is really well, but you commented that if not initialize emp its output garvage value but such as not and one more prablem tiger is not print also when write in printf fuction why?
Please run the proram and explain again it.

@Mr.Sivaraman.
struct emp means defining a structure with the name emp.
Structure is a collection of heterogeneous elements. Here the structure contains 3 variables name (it is an array), age and salary. Here e is the object to the structure.

Hi Bhuvana, the structure is initialized in the statement
struct emp e = {"Tiger"};
So all other structure members are initialized to null. Note that initialization order should be same as the member definition order.
struct emp e = {"Tiger"};

If we not give size of name than error will come
"In function 'main':
Line 6: error: flexible array member not at end of struct"
why?
"In function 'main':
Line 6: error: flexible array member not at end of struct"
why?

If we initialize member of the structure like this : e.name = "tiger"; then it is giving garbage value of age. Why? Anyone explain it.
