| void main()
{
int s[4][2]={ {1234,56},{1212,33},{1434,80},{1312,78} };
int (*p)[2];
int i,j,*pint;
for(i=0;i<=3;i++)
{
p=&s[i];
pint=p;
printf("\n");
for(j=0;j<=1;j++)
printf("%d",*(pint+j));
}
} while running this program it shows a warning-suspicious
pointer conversion ie pint=p; my que is why should we assign
the value of p to pint again.why cant we use it directly as
*(p+j)..but if i use like tat the o/p is garbage value.. | | 1 |
