Question 1

What will be the output of the program ?

#include<stdio.h>

int main()
{
    char str[7] = "ExamAdept";
    printf("%s\n", str);
    return 0;
}

Answer

Answer: C

Here str[] has declared as 7 character array and into a 8 character is stored. This will result in overwriting of the byte beyond 7 byte reserved for '\0'.

Question 2

What will be the output of the program ?

#include<stdio.h>

int main()
{
    printf("India", "BIX\n");
    return 0;
}

Question 3

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

Answer: D

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

Question 4

What will be the output of the program ?

#include<stdio.h>
#include<string.h>

int main()
{
    char str[] = "India\0\BIX\0";
    printf("%s\n", str);
    return 0;
}

Answer

Answer: B

A string is a collection of characters terminated by '\0'.

Step 1: char str[] = "India\0\BIX\0"; The variable str is declared as an array of characters and initialized with value "India"

Step 2: printf("%s\n", str); It prints the value of the str.

The output of the program is "India".
