Help with exiting my Program

Hi,

I am writing a program where the user has to input 10 temperatures and then select an option on what to do with the 10 temps. I am having problems with the exit part of the program. I want it to exit when the user inputs the letter e. Thank you in advance for your opinions and help. Here is my program:

//Source Code -> Temp.c
//Purpose ->To work with array of MAX temps, to define a constant for the array size, to use sort and search algorithms, and to write a menu driven program.

#include<stdio.h>
#include<math.h>
#define MaxTemp 10

void getTemps(int[],int);
void printTemps(int[],int);
void AvgTemps(int[],int);
void HighTemps(int[],int);
void LowTemps(int[],int);
void SortTemps(int[],int);

int main(void)

{
	
	int option;
	int Temps[MaxTemp] = {0};
	
do
{

	printf("\n Temperature Calc:\n\n");
	printf("\n 1. Input Temperatures");
	printf("\n 2. Print Temperatures");
	printf("\n 3. Print Temperature Average");
	printf("\n 4. Print the Highest Temperature");
	printf("\n 5. Print the Lowest Temperature");
	printf("\n 6. Sort Temperature:");
	printf("\n 7. Press 'E' in operation to exit\n\n");
	printf("Please select a number:");
	scanf("%d", &option);


switch(option)

{

	case 1: 
	
	printf("Input \n");
	getTemps(Temps,10);

	break;

	
	case 2:

	printf("Show Temps\n");
	printTemps(Temps,10);
	break;
	
	case 3:
	
	printf("Average\n");
	AvgTemps(Temps,10);

	break;
	
	case 4:

	printf("High\n");
	HighTemps(Temps,10);
	break;
	
	case 5:
	
	printf("Low\n");
	LowTemps(Temps,10);
	break;
	
	case 6:
	
	printf("Sort\n");
	SortTemps(Temps,10);
	break;


	default: 
		
	printf ("Error");


	

}	

}while(option != 'E');


return 0;

}



void getTemps(int temp[], int size)

	{
		int counter = 0;
		for(counter = 0; counter < size; counter++)
		{
			printf("Enter Temp %d:\n", counter + 1);
			scanf("%d", &temp[counter]);
		}
}

void printTemps(int temp[], int size)

	{
		int counter = 0;
		for(counter = 0; counter < size; counter++)
		{
		 printf("Temperature %d \n", temp[counter]);
		}
}

void AvgTemps(int temp[], int size)

	{
		int counter = 0;
		int AvgTemps = 0;
		int average = 0;
		for(counter = 0; counter < size; counter++)
		{
			AvgTemps +=temp[counter];
		}

		AvgTemps  /= size;
		printf("average %d \n", AvgTemps);
}


void HighTemps(int temp[], int size)

	{
		int counter = 0;
		int high = -1000; 
		for(counter = 0; counter < size; counter++)
		{
			if(high < temp[counter])
				high = temp[counter];
			
			
	}
printf("high %d \n", high);

}
void LowTemps(int temp[], int size)

	{
		int counter = 0;
		int low = 1000; 
		for(counter = 0; counter < size; counter++)
		{
			if(low > temp[counter])
				low = temp[counter];
			
			

	}
printf("low %d \n", low);

}

void SortTemps(int temp[], int size)
{
	int counter1,counter2;
	int tempValue;

	for(counter1=0; counter1 < size - 1; counter1++)
		for(counter2 = 0; counter2 < size -1-counter1; counter2++)
			if(temp[counter2 + 1] < temp[counter2])
			{
				tempValue = temp[counter2];
				temp[counter2] = temp[counter2 + 1];
				temp[counter2 + 1] = tempValue;

		
					}
	}
