    Question 1

    Predict the output of following program. Assume that the numbers are stored in 2's complement form. C 
    #include<stdio.h> 
int  main() 
{ 
   unsigned int x = -1; 
   int y = ~0; 
   if (x == y) 
      printf("same"); 
   else
      printf("not same"); 
   return 0; 
}
    • A
      same
    • B
      not same

    1. short int x;
    C 
    2. signed short x;
    C 
    3. short x;
    C 
    4. unsigned short x;
    • A

    • C
      1
    • D
      All are valid

    Question 3

    Predict the output C 
    #include <stdio.h>

int main()
{
   float c = 5.0;
   printf ("Temperature in Fahrenheit is %.2f", (9/5)*c + 32);
   return 0;
}
    • A
      Temperature in Fahrenheit is 41.00

    printf("%v", *vptr);
    getchar();
    return 0;
}
    • A
      0
    • B
      Compiler Error
    • C
      Garbage Value

    Question 7

    Assume that the size of char is 1 byte and negatives are stored in 2's complement form C 
    #include<stdio.h>
int main()
{
    char c = 125;
    c = c+10;
    printf("%d", c);
    return 0;
}
    • A

    • B
      +INF
    • C
      -121
    • D
      -8

    Question 8

    C 
    #include <stdio.h>
int main()
{
    if (sizeof(int) > -1)
        printf("Yes");
    else
        printf("No");
    return 0;
}
    • A

        printf("IF");
    else if (x == 0.1f)
        printf("ELSE IF");
    else
        printf("ELSE");
}
    • A
      ELSE IF
    • B
      IF
    • C
      ELSE

    Question 10

    Suppose n and p are unsigned int variables in a C program. We wish to set p to nC3. If n is large, which of the following statements is most likely to set p correctly?

    • A

      p = n * (n-1) * (n-2) / 6;

    • B

      p = n * (n-1) / 2 * (n-2) / 3;

    • C

      p = n * (n-1) / 3 * (n-2) / 2;

    • D

      p = n * (n-1) * (n-2) / 6.0;
