Question { 4169 }

write the output of following code ..

main()

{

static int a[]={10,20,30,40,50};

int *ptr=a;

static int arr[2][2]={1,2,3,4};

char str[]="ABCD * 4#";

char *s=str+2;

int i,j;

for(i=0;i<5,i++)

printf("%d",*ptr++);

for(i=0;i<2;i++)

for(j=0;j<2;j++)

printf("%d\n",*(*(n+i)+j));

printf("%c\n%c\n%c\n",*(str+2),*s++,*--s);

}

Answer

There is a compilation error in the line.
printf("%d\n",*(*(n+i)+j)); as n is not defined. If we
assume arr in place of n then the output is:
