# Test the Ruby string class.

# Code for 7/23:

# Create two strings:
a = "rabbit"
b = String.new("raccoon")

# Print lengths of strings:
print a.length, " ", b.length, "\n"

# Convert a to uppercase with nondestructive method:
c = a.upcase
print c, " ", a, "\n"

# Convert a to uppercase with destructive method:
a.upcase!
print a, "\n"

# Test if strings are equal:
print a.eql?(b), " ", a.eql?(a), " ", a == b, " ", a == a, "\n"

# Code for 7/25:

# Insert string "abc" into b:
b.insert(3, "abc")
print b, "\n"

# Find the index of the substring "coo":
print b.index("coo"), "\n"

# Test to_i method:
d = "345"
print d.to_i + 1, "\n"

# Test replication operator:
print a * 3, "\n"
print (a + " ") * 3, "\n"
