Question

there are two string variables, s1 and s2, that have already been declared and initialized. write some code that exchanges their values.

Answer 1

Answer:Here's some sample code in Python to exchange the values of two string variables, s1 and s2:

Explanation:

makefile

Copy code

s1 = "hello"

s2 = "world"

# print original values

print("s1 =", s1)

print("s2 =", s2)

# swap values using a temporary variable

temp = s1

s1 = s2

s2 = temp

# print swapped values

print("s1 =", s1)

print("s2 =", s2)

This code first initializes the two string variables, s1 and s2, with some initial values. It then prints out the original values.

Next, it uses a temporary variable, temp, to swap the values of s1 and s2. This is done by first storing the value of s1 in temp, then assigning the value of s2 to s1, and finally assigning the value of temp to s2.

Finally, the code prints out the swapped values of s1 and s2. After the code has executed, the value of s1 will be the original value of s2, and the value of s2 will be the original value of s1.
