b) if (X!=0) Y ;else Z

c) if (X==0) Y ; Z

Ans. (b)

Q5. From the following program

foo()

int foo(int a, int b)

{

if (a&b) return 1;

return 0;

}

a) if either a or b are zero returns always 0

b) if both a & b are non zero returns always 1

c) if both a and b are negative returns 0

Q6. The following function gives some error. What changes have to be made

void ( int a,int b)

{

int t; t=a; a=b; b=t;

}

a) define void as int and write return t

b) change everywhere a to *a and b to *b

Q7. Which of the following is incorrect

a) if a and b are defined as int arrays then (a==b) can never be true

b) parameters are passed to functions only by values

c) defining functions in nested loops

Q8. include

void swap(int*,int*);

main()

{

int arr[8]={36,8,97,0,161,164,3,9}

for (int i=0; i<7; i++)

{

for (int j=i+1; j<8;j++)

if(arr[i]

}

}

void swap(int*x,int*y)

{

int temp; static int cnt=0;

temp= *x;

*x=*y;

*y=temp;

cnt++;

}

What is cnt equal to

a) 7

b) 15

c) 1

d) none of these

Q9. int main()

{

FILE *fp;

fp=fopen("test.dat","w");

fprintf(fp,'hello\n");

fclose(fp);

fp=fopen ("test.dat","w");

fprintf (fp, "world");

fclose(fp);

return 0;

}


If text.dat file is already present after compiling and execution how many bytes does the file occupy ?

a) 0 bytes

b) 5 bytes

c) 11 bytes

d) data is insufficient

Q10. f1(int*x,intflag)

int *y;

*y=*x+3;

switch(flag)

{

case 0:

*x=*y+1;

break;

case 1:

*x=*y;

break;

case 2:

*x=*y-1;

break;

}

return(*y)

main()

{

*x=5;

i=f1(x,0); j=f1(x,1);

printf("%d %d %d ",i,j,*x);

}

What is the output?

a) 8 8 8

b) 5 8 8

c) 8 5 8

d) none of these
