A No correction required

B were to be cheated

C had been cheating

Q2:
Point out the error in the following program (if it is compiled with Turbo C compiler). 
#include<stdio.h>
int main()
{
    display();
    return 0;
}
void display()
{
    printf('AptitudeCrack.com');
}

A No error

B
display() is called before it is defined

C None of these

D
display() doesn't get invoked

Q3: Point out the error in the program? 
#include<stdio.h>

int main()
{
    struct bits
    {
        float f:2;
    }bit;

    printf('%d\n', sizeof(bit));
    return 0;
}

A Error: Invalid member access in structure

B 2

C 4

D
Error: cannot set bit field for float

Q4: Point out the error in the program? 
#include<stdio.h>

int main()
{
    struct emp
    {
        char name[25];
        int age;
        float bs;
    };
    struct emp e;
    e.name = 'Suresh';
    e.age = 25;
    printf('%s %d\n', e.name, e.age);
    return 0;
}

A No error, Output: Suresh 25

B Error: Rvalue required

C Error: invalid constant expression

D Error: Lvalue required/incompatible types in assignment

Q5: Which of the following statements correct about the below program? 
#include<stdio.h>

int main()
{
    struct emp
    {
        char name[25];
        int age;
        float sal;
    };
    struct emp e[2];
    int i=0;
    for(i=0; i<2; i++)
        scanf('%s %d %f', e[i].name, &e[i].age, &e[i].sal);

    for(i=0; i<2; i++)
        scanf('%s %d %f', e[i].name, e[i].age, e[i].sal);
    return 0;
}

A The code runs successfully.

B Error: scanf() function cannot be used for structures elements.

C Error: Floating point formats not linked Abnormal program termination.

D Error: structure variable must be initialized.

Q6: Which of the following statements correct about the below program? 
#include<stdio.h>

int main()
{
    union a
    {
        int i;
        char ch[2];
    };
    union a u1 = {512};
    union a u2 = {0, 2};
    return 0;
}
1: u2 CANNOT be initialized as shown.
2: u1 can be initialized as shown.
3: To initialize char ch[] of u2 '.' operator should be used.
4: The code causes an error 'Declaration syntax error'

A 1, 2, 3

B 2, 3

C 1, 2

D 1, 3, 4

        int month;
        int year;
    };
int main()
{
    struct date d;
    struct date *pdt;
    pdt = &d;
    return 0;
}

A d.month = 12

B &pdt.month = 12

C pdt.month = 12

D pdt->month = 12
