Answer / mansi_engg

use unsigned before variable a and b in
a=1;
b=32767;
a=a+b;
b=a-b;
a=a-b;
bcoj 32767+1 =32768 which goes out of range of integer and
will be stored as -32768 which wil make the swapping
wrong.by using unsigned, addition will come in range 0-65536
and thus the process works.

Answer / sharath kumar

As int max valur is 32767. If we increment it it becomes -32768, so its a wrong way to do

a=1; b=32767;
a=-a; b=-b;
a=a+b; //-32768 with in range
b=a-b; //-1
a=a-b; //-32767
printf("%d%d",-a,-b);

Answer / g.sai lakshmi priyanka

void main()
{
int a,b;
a=32767,b=1;
a=a*b;
b=a/b;
a=a/b;
printf("%d %d",a,b);
}
EXPLAINATION:

a=32767*1=32767
b=32767/1=32767
a=32767/32767=1

a=1,b=32767

Answer / mani654mani

Int var1=1, var2=32767;
var1 = var1 + var2;
var1 = 1 + 32767 =32768;

var2 = var1 - var2;
var2 = 32768 - 32767 = 1;

var1 = var1 - var2;
var1 = 32768 - 1 = 32767;

So Now var1 = 32767 and var2 = 1
