| You are given a string which contains some special
characters. You also have set of special characters. You are
given other string (call it as pattern string). Your job is
to write a program to replace each special characters in
given string by pattern string. You are not allowed to
create new resulting string. You need to allocate some new
memory to given existing string but constraint is you can
only allocate memory one time. Allocate memory exactly what
you need not more not less. | Microsoft | 2 |
| 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 |
