# Step 1: Create two data frames with the same columns
df1 <- data.frame(col1 = c(1, 2), col2 = c("a", "b"))
df2 <- data.frame(col1 = c(3, 4), col2 = c("c", "d"))

print(df1)
print(df2)
# Step 2: Use rbind to combine the two data frames by row
combined_df <- rbind(df1, df2)

# Step 3: Print the resulting data frame
print(combined_df)
