What is the Algorithm for exchanging values of two variables?
There are three primary algorithms to exchange the values of two variables. Exchange with Temporary Variable temp = a; a = b; b = temp; Exchange Without Temporary Variable Using Exclusive Or a = a ^ b; b = b ^ a; a = a ^ b; Exchange Without Temporary Variable Using Arithmetic a = a + b; b = b - a; a = a - b;

How do you write xy in c program?
Assuming that x and y are two variables, such as they might be in Algebra, and that the expression "xy" is meant to be the multiplication of x times y, you would write it as x * y This expression could be used with a third variable in an assignment statement, or as a condition in an if statement where it can be compared to another variable or a constant.

Why does programmer need variable?
Variables can maintain the same value throughout a program, or they can change values several times, depending on your needs. when you put a variable in a program, the computer recognises the variable and you can change it's value throughout without an error. Note: You can write programs without variables, but their functionality will be quite restricted, like this: int main (void) { puts ("hello, world"); return 0; }
Can you write a program without main in c?

How do we write c program without using swap to interchange values by accessing another variable?
