Comment

// Another approach, that doesn't requires to create a third variable,
// but requires more computation

int a = 7;
int b = 2;

a = a ^ b;
b = a ^ b;
a = a ^ b;

// ^ means XOR
// if you want a more concise code, you can do
// a ^= b;
// b ^= a;
// a ^= b;

swapping data of two variable without third one

Comment

X= 25 (First number), Y= 23 (second number)
Swapping Logic:
X = X + Y = 25 +23 = 48
Y = X - Y = 48 - 23 = 25
X = X -Y = 48 - 25 = 23
and the numbers are swapped as X =23 and Y =25.
