What will be the output of the program If characters 'a', 'b' and 'c' enter are supplied as input?
#include<stdio.h>
int main()
{
void fun();
fun();
printf("\n");
return 0;
}
void fun()
{
char c;
if((c = getchar())!= '\n')
fun();
printf("%c", c);
}
Answer: Option
Explanation:
Step 1: void fun(); This is the prototype for the function fun().
Step 2: fun(); The function fun() is called here.
The function fun() gets a character input and the input is terminated by an enter key(New line character). It prints the given character in the reverse order.
The given input characters are "abc"
Output: cba
