First take 2's complement of -3 which will be as: 3 = 0000 0011 // binary value of 3 = 1111 1100 // take 1's complement i.e invert 0's & 1's 2's complement = 1111 1101 // add 1
We have got result for -3. Now operation for ~ (1's complement is pending). We know in 1's complement 0's will replaced by 1's & 1's will be replaced by 0's as we did above in second step.
Therefore 1's complement of 1111 1101 will be = 0000 0010 Result = 2

hi TRINATH SOMAROUTHU
Thank you for posting another solution
#define swap(x,y) x^=y^=x^=y
void main()
{
int a=10,b=20;
swap(a,b);
clrscr();
printf("%d %d" ,a,b);
getch();
}
output: 20 10
void main()
{
int a,b,c;
clrscr();
printf("\n Enter two no ");
scanf("%d%d",&a,&b);
printf("\n Before Swaping value of a and b %d %d",a,b);
c=a;
a=b;
b=c;
printf("\n After Swaping value of a and b %d %d",a,b);
getch();
}
THANKS ,THANKS A LOT
good job..
please solve the problem
int a=~-3;
actually i do,not understand about ~ operator that how exactly it works .please solve step by step
process 4 is not working
error is 'wrong type argument to bit-complement' in float value
can anybody explain in detail how a=a+b-(b=a); will work out for swapping
its using third var...
Here is couple of more way to swap two numbers without using temp variable in Java
learn c programming and c graphics from programmingcampus
where you can get best online tutorials which make simple and easy to your learning.
a=a+b
a=a-b
b=a-b
thank u very much. this is the best solution without using third variable. simple and short
u r most welcome
a=a+b-(b=a)
now since value of a will be assigned to b
so equation will be
a=a+b-(a)
a=b
read the question first. we don't have to use third variable.
HI can u please help me to solve the following
Swap the values in 2 variBles using a third variAble?? Plzzzzz rply its urgent
Process 1 & 5 are approx same.
First take 2's complement of -3 which will be as:
3
= 0000 0011 // binary value of 3
= 1111 1100 // take 1's complement i.e invert 0's & 1's
2's complement = 1111 1101 // add 1
We have got result for -3. Now operation for ~ (1's complement is pending). We know in 1's complement 0's will replaced by 1's & 1's will be replaced by 0's as we did above in second step.
Therefore 1's complement of 1111 1101 will be =
0000 0010
Result = 2
Hi trinath your this program do my help & made my image in class is a intelligenc boy so thenku very much
I have got another simple solution for this.
A=A*B
B=A/B
A=A/B
Swaping done.
@Ashok Natarajan this is also correct when given both values some numbers.. if your give A=0,B=4 that time floating exception will happen..
the right order is a=a+b,b=a-b,a=a-b
Swapping of two numbers can be done in 5 methods u can see in following url...
www.programmerschat.blogspot.in
yupp...its correct order..(y)
one more way
#include
#include
int main( )
{
static int a=2,b=5;
a=a*b;
b=a/b;
a=a/b;
printf(" a =%d\t b=%d",a,b);
}
void main()
{
int a,b;
clrscr();
printf("\n Enter two no :");
scanf("%d%d",&a,&b);
printf("\n Before Swaping value of a and b %d %d",a,b);
b=a+b-(a=b);
printf("\n After Swaping value of a and b %d %d",a,b);
getch();
}
process 4 is not working. I things it's
b= b - ~a - 1;
a= a + ~b +1;
what u say?
if do not use third variable then
How to swap 2 variable using only assignment operator and no other operator in C
