void main()
{
fun1();
printf(" ");
fun1();
printf(" ");
fun1();
printf(" ");
}
fun1()
{
static int b = 10;
b++;
printf("%d", b++);

printf(" ");
printf("%d", b++);
}

B 11 12 11 12 11 12
C 11 12 14 12 14 12
D Error "static variable re-assignment"
2. State o/p
#include
int main()
{ 123456789
printf("%d",-16["WHAT A PLAYER WHAT A PLAYER SLUMDOG!!!"]);
return 0;
}
A. Error
B. GARBAGE
c. 65
D.none of the above
3. state o/p
main()
{
char x = 0x8A;
unsigned int y = x;
printf("%d\n", y);
}
A -118
B 138
C 118

4. state o/p
#include
#include
int main()
{
printf("%c\n", 'mujhe khoon do main tumhe pani duungah' -3);
return 0;
}
A warning,Outputs: -h
B error
c warning, Outputs: e
d warning, Outputs: n
e warning, Outputs: (ascii value of h)
5. #include
int main()
{
struct {
int i;
char j;
long k;
}b;
&b.k - &b;
}
Is this error ?
A Yes
B No
Give reasons
6. O/p
#include
int main()
{
int x=10;
printf("%d",++x+x++
printf("this world is good and ");
else printf("not so bad after all ");
if(7.7>b)

else printf("not so bad after all");
}
A not so bad after all not so bad after all
B this world is good and this world is good
C this world is good and not so bad after all
D not so bad after all this world is good
10. Which of the following is the correct output for the program given below?
main()

11. In the program given below, point out the error, if any, in the while loop?
main() {
int i=1;
while()
{ printf("%d",i++);
if(i>10) break; }
}
1.the condtion in the while loop is must
2.There should be atleast a semicolon in the while()
3.The while loop should be replaced by the for loop
4.No Error
12. Which of the following is the correct output for the program given below?

main() {
int i, x=10, y=100%90;
for(i=1;i<=10;i++) if(x!=y) printf("x=%d y=%d", x,y); } 1.The printf() function is called 10 times 2.The program will produce the output x=10 y=10 3.The program will not produce any output 4.the printf() function is called infinite times 14.Predict o/p void myFunc (int x) { if (x > 0)
