Print values

of a & b

Declare variables &

assign values to a & b.

a = a + b;

b = a − b;

a = a − b;

Flowchart:

Hint: Copy value of a in third variable c, value of b in a, and value of c in b.

Explanation:

In the above cited program, first three variables a, b, & c are declared. The program invokes

two values of a & b from user. The user assigns values to the variables a & b.

Now copy the value of a in third variable c, value of b in a, and value of c in b.

Here, when we assign the value of a to c (c = a), the value of a is copied in variable c. When we

assign (a = b), the value of b is copied in variable ...
