In C code please, thank you!

Prompt the user to enter the time of the day. The user should enter d for daytime and n for nighttime. Configure a boolean variable to store if it is daytime (true) or nighttime (false). Use the boolean variable to store if it is daytime or nighttime and print if the temperature is ideal if it needs to be raised if it needs to be lowered, and by how much. If a Boolean variable is not used, there will be a 20% grade penalty Ideal temperatures: Daytime 21.2 C Nighttime: 18.3C Sample Output Day (d) or Night (n):n Enter the current temperature: 12 You need to raise the temperature by 6.3 degrees. Sample Output Day (d) or Night (n):d Enter the current temperature:21.2 The temperature is ideal. Sample Output Day (d) or Night (n):n Enter the current temperature:18.3 The temperature is ideal. Have a good night's sleep. Sample Output Day (d) or Night (n):d Enter the current temperature:25.5 You need to lower the temperature by 4.3 degrees
