Ans. no error. But It will over writes on same file.
What are the output(s) for the following ?
Q6. #include
Q7. #define MAN(x,y) (x)>(y)?(x):(y) { int i=10;j=5;k=0; k= MAX(i++,++j) printf(%d %d %d %d,i,j,k) }
Ans. 10 5 0

Q19. .main() { char *p = "hello world!"; p[0] = 'H'; printf("%s",p); }
Q1. typedef struct{ char *; nodeptr next; } * nodeptr ;
What does nodeptr stand for?
Q2. What does. int *x[](); means ?
Q3. struct list{ int x; struct list *next; }*head; the struct head.x =100 Is the above assignment to pointer is correct or wrong ?
Ans. Wrong
Q4.What is the output of the following ? int i; i=1; i=i+2*i++; printf(%d,i);
Ans. 4
Q5. FILE *fp1,*fp2; fp1=fopen("one","w") fp2=fopen("one","w") fputc('A',fp1) fputc('B',fp2) fclose(fp1) fclose(fp2)}a.error b. c. d.
Ans. no error. But It will over writes on same file.

SECTION A:
1. THERE WERE 750 PEOPLE WHEN THE FIRST SONG WAS SUNG. AFTER EACHSONG 50 PEOPLE ARE LEAVING THE HALL. HOWMANY SONGS ARE SUNG TO MAKETHEM ZERO?ANS:16
SECTION B:
1. typedef struct{ char *; nodeptr next; } * nodeptr;what does nodeptr stand for?ans:
2. 2 oranges,3 bananas and 4 apples cost Rs.15 . 3 ornages 2 bananas 1 apple costs Rs 10. what is the cost of 3 oranges, 3 bananas and 3 apples ANs Rs 15.
3. int *x[](); meansAns:expl: Elments of an array can't be functions.
4. struct list{int x;struct list *next;}*head;the struct head.x =100Ans: above is correct / wrongexpl: Before using the ptr type struct variable we have to give memory to that .And also when ever the struct variable is ptr then we access themembers by "->" operator.
