6. Give sizeof(a) in bytes for the following: (assume 32bit PC)
char *a[10];
char (*a)[10];
char (**a)[20];
char (*a)(int x, char c);
Ans: 40 , 4 , 4 , 4
7. Find out the output :
#include<stdio.h>
main()
{
int n1 = 10, n2 = 12;
if( n2=!0)
printf("Result is:%d\n",(n1/n2));
else
printf("cannot divide by zero\n");
}
Ans: Result is:10
8. Find out the output:
#include<stdio.h>
main()
{
long int one_million;
one_million=1,000,000;
printf("One million is %d",one_million);
}
Ans: One million is 1
9. what is the output ?
#include<stdio.h>
#define f(a,b) a##b
#define g(a) #a
#define h(a) g(a)
main()
{
printf("%s %s\n",h(f(1,2)),g(f(1,2)));
}
Ans: 12 f(1,2)
10. what is the output?
#include<stdio.h>
main()
{
static int j=printf("%d",456);;
printf("%d",j);
}
Ans: Error
11. What is the output ?
#include<stdio.h>
main()
{
int i = 5;
int j;
j=sizeof(i++);
printf("%d",i);
}
Ans: 5
12. What is the output of z?
#include<stdio.h>
main()
{
int z,x=5,y=-10,a=4,b=2;
z=x++ - --y * b / a;
}
Ans: 10
