Thread: HELP! How do I execute a function in a switch statement??

Assuming i already have a readImage function, how do i prompt the user to call it by typing in "Sailing"?

instructions:

1.3.1 Load a PPM Image
This option prompts the user for the name of an image file. You don't have to implement a file reading
function; just use the provided one, ReadImage. Once option 1 is selected, the following should be shown:
Please input the file name to load: sailing
After a name, for example sailing, is entered, the PhotoLab will load the file sailing.ppm. Note that, in
this assignment please always enter file names without the extension when you load or save a file (i.e. enter
'sailing', instead of 'sailing.ppm'). If it is read correctly, the following is shown:
Please make your choice: 1
Please input the file name to load: sailing
sailing.ppm was read successfully!
--------------------------------
1: Load a PPM image
2: Save an image in PPM and JPEG format
3: Change a color image to black and white
4: Make a negative of an image
5: Flip an image horizontally
2
6: Mirror an image horizontally
7: Flip an image vertically
8: Mirror an image vertically
9: Test all functions
10: Exit
Please make your choice:
Then, you can select other options. If there is a reading error, for example the file name is entered incorrectly
or the file does not exist, the following message is shown:
Cannot open file "sailing.ppm.ppm" for reading!


This is what i have so far i dont know how to use a switch statement to call the function readImage becuase I already have a printf statement in it. HELP

Code:

int main(void)
{
	int c;
	char name;

	do
	{
		printf("1: Load a PPM image\n");
		printf("2: Save an image in PPM and JPEG format\n");
		printf("3: Change a color image to black and white\n");
		printf("4: Make a negative of an image\n");
		printf("5: Flip an image horizontally\n");
		printf("6: Mirror an image vertically\n");
		printf("7: Flip an image vertically\n");
		printf("8: Mirror an image vertically\n");
		printf("9: Test all functions\n");
		printf("10: Exit\n");
		printf("Please make your choice: \n");
		scanf("%d",&c);
	

		switch(c)
		{
		case 1: 
			printf("Please input the file name to load: \n");
			scanf("%s",name);
			readImage?
				
			break;
		}
	}
