What will be the output of the program? #include<stdio.h> int main() { int i; char a[] = "\0"; if(printf("%s", a)) printf("The string is not empty "); else printf("The string is empty "); return 0; }

The string is not empty
The string is empty
No output
0

Correct Answer: The string is empty

Explanation:

The function printf() returns the number of charecters printed on the console.

Step 1: char a[] = '\0'; The variable a is declared as an array of characters and it initialized with "\0". It denotes that the string is empty.

Step 2: if(printf("%s", a)) The printf() statement does not print anything, so it returns '0'(zero). Hence the if condition is failed.

In the else part it prints "The string is empty".
