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..

p ia pointer to an array when p is incremented it will increment by the number of elements in the array...
for example
int (*p)[2]; //it is aponiter to an arry of 2 elements so when we do p+1 then it will be incremented by two*(sizeof(int))
so leading to the garbage value at the last loop..
can be properly analyzed by the below program
#include<stdio.h>
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("%p.....%d\n",*(p+j),**(p+j));
}
}
4.weight conversion:
Write a program that will read weight in pounds and convert
it into grams.print both the original weight and the
converted value.There are 454 grams in a pound.design and
carry out a test plan for this program.
I need to take a sentence from input and sort the words
alphabetically using the C programming language.
Note: This is C not C++.
qsort and strtok not allowed
plz answer....A program that takes 3 variables e.g a,b,c in
as seperate parameters and rotates the values stored so
that value goes a to b, b to c and c to a .
