Hello! I was wondering how I would be able to create a menu to select Characters instead of numbers.

Currently this is what i have:

Code:
int menu(){
    int choice;
    cls;
       printf("\n\n==============================\n");
       printf("   MY FIRST ARRAY ASSIGNMENT ");
       printf("\n==============================\n");
       printf("L - oad the Array\n");
       printf("M - inimum value from the Array\n");
       printf("H - ighest value from the Array\n");
       printf("A - verage of all values in the Array\n");
       printf("O - utput the values in the Array\n");
       printf("Q - uit\n");
       printf("==============================\n");
       printf("\t Enter Menu Choices: ");
       scanf("%i", &choice);
       
       switch(choice){
                      case 1:                          
                      loadArray(grades);
                           break;                           
                      case 2:
                           break;                           
                      case 3:                          
                           break;
                      case 4:      
                           break;
                      case 5: 
                           break;
                      case 6:
                           break;
                      default:
                              printf("You must enter a L,M,H,A,O,Q only!\n");
                              pause;
                           break;
       } // End of switch
       } // End of Function

I want each case to select from: L M H A O Q, instead of 1-6


thank you!
