Need Help my fellow GURU's

I'm trying to figure out where to start my school assignment. I could post it if someone is willing to help me out. I would really appreciate it. Its in C language. I have to make a function about some bacterial growth.

 

Pure C? Or C++?

 

Pure C. Here is the link. Thanks for the reply.

 

If someone could put me on the right direction I could start.

 

Your code should ask user for 3 input values:

One of the approach to the coding is to write down all the lines of the task into the source code as the comments.

Code:

void main(int argc, char* argv)
{
// 1. Ask the user for the size of the container (1 to 8 ONLY) (MUST BE VALIDATED)
// 2. Ask the user for the level of nutrients in the growth medium (0 to 3 ONLY) (MUST BE VALIDATED)
// 3. Ask the user for the temperature to grow the bacteria in Celsius (20 to 54 ONLY) (MUST BE VALIDATED).
}

And then start to dive into each line:

Code:

void main(int argc, char* argv)
{
// 1. Ask the user for the size of the container (1 to 8 ONLY) (MUST BE VALIDATED)
// 1.1. Print the line which will ask the user to enter the size of the container
// 1.2. Read the line of the user`s input
// 1.3. Convert the line into the number
// 1.4. Compare the number with given limits
// 2. Ask the user for the level of nutrients in the growth medium (0 to 3 ONLY) (MUST BE VALIDATED)
// 2.1. Print the line which will ask the user to enter the level of nutrients in the growth medium
// 2.2. Read the line of the user`s input
// 2.3. Convert the line into the number
// 2.4. Compare the number with given limits
// 3. Ask the user for the temperature to grow the bacteria in Celsius (20 to 54 ONLY) (MUST BE VALIDATED).
// 3.1. Print the line which will ask the user to enter the temperature to grow the bacteria in Celsius
// 3.2. Read the line of the user`s input
// 3.3. Convert the line into the number
// 3.4. Compare the number with given limits
}

You can see that steps 1,2,3 have the same actions - print the prompt, get the line from user, convert the line (string) to number, compare the number with limits - these actions are the candidates for 4 simple functions or one big function with 4 steps.
Like:

Code:

int GetValueFromUser(char* prompt, int limitMin, int limitMax)
{
// 1. Print the prompt
// 2. Read the line of the user`s input
// 3. Convert the line into the number
// 4. Compare the number with given limits limitMin and limitMax
}

void main(int argc, char* argv)
{
int containerSize;
int nutrientsLevel;
int temperature;
// 1. Ask the user for the size of the container (1 to 8 ONLY) (MUST BE VALIDATED)
containerSize = GetValueFromUser("Please enter the size of container (in feet)", 1, 8);

// 2. Ask the user for the level of nutrients in the growth medium (0 to 3 ONLY) (MUST BE VALIDATED)
nutrientsLevel = GetValueFromUser("Please enter the level of nutrients", 0, 3);

// 3. Ask the user for the temperature to grow the bacteria in Celsius (20 to 54 ONLY) (MUST BE VALIDATED).
temperature = GetValueFromUser("Please enter the temperature (in Celsius)", 20, 54);
}
