Thread: project help (mead,median,mode)

Hi ppl i have being workig on this project for weeks and im a novice when it comes to c programming so if any1 can help please do so.

im trying to make a program where the user is asked if they would like to enter (4-20) numbers manually or randomly generate (4-200) numbers. Display whichever choice, then if they would like to display the mean, median, mode or all three. Afterwards the program should ask if the user would like to repeat the program or exit.

this was my plan:

Would you like to: 1 - manually enter (4-20) numbers
2 - randomly generate (4-200) numbers

Then ask: which would you like to display :1- Mean
2 - Median
3 - Mode
4 - All three

Would you like to repeat the program: 1 - Yes
2 - No

My code so far as you can tell i am quite bad at it:

Code:

#include<stdio.h>
#include<math.h>

main() {
  float a,b;
  int instr;
  
  int one;
    int two;
    int three;
    int four;
    int five;
    int six;
    int seven;
    int eight;
    int nine;
    int ten;
    int eleven;
    int twelve;
    int thirteen;
    int fourteen;
    int fifthteen;
    int sixteen;
    int seventeen;
    int eighteen;
    int nineteen;
    int twenty;
    int m;
    
  printf("Welcome!!!\n\nThis Program Calculates the Mean, Median and Mode of:\n\na. Manually Entered Numbers Ranging Between 4-20 or\n\nb. Randomly Generated numbers ranging from 4-200 ");
  
  printf("\n\n\n\nPlease Make A choice\n\n1. for Random Numbers(4-200)\n\n2. for Manually entering Numbers(4-20): ");
  scanf("%d[20]",&instr);
  
  if (instr == 1) {
    printf("The random Numbers are:"\n);
  }
else {
    if (instr == 2) {
      printf("Please Enter Your Values (4-20)\n");
    

    
    
    
    
   { 
    printf("Enter value one: \n");
  scanf("%f",&one);
    
   printf("Enter value two: \n");
  scanf("%f",&two); 
  
  printf("Enter value three: \n");
  scanf("%f",&three);
        
   printf("Enter value four: \n");
  scanf("%f",&four);     
        
   printf("Enter value five: \n");
  scanf("%f",&five);
  
  printf("Enter value six: \n");
  scanf("%f",&six);
  
  printf("Enter value seven: \n");
  scanf("%f",&seven);
  
  printf("Enter value eight: \n");
  scanf("%f",&eight);
  
  printf("Enter value nine: \n");
  scanf("%f",&nine);
  
  printf("Enter value ten: \n");
  scanf("%f",&ten);
  
  printf("Enter value eleven: \n");
  scanf("%f",&eleven);
  
  printf("Enter value twelve: \n");
  scanf("%f",&twelve);
  
  printf("Enter value thirteen: \n");
  scanf("%f",&thirteen);
  
  printf("Enter value fourteen: \n");
  scanf("%f",&fourteen);
  
  printf("Enter value fifteen: \n");
  scanf("%f",&fifteen);
  
  printf("Enter value sixteen: \n");
  scanf("%f",&sixteen);
  
  printf("Enter value seventeen: \n");
  scanf("%f",&seventeen);
  
  printf("Enter value eighteen: \n");
  scanf("%f",&eighteen);
  
  printf("Enter value nineteen: \n");
  scanf("%f",&nineteen);
  
  printf("Enter value twenty: \n");
  scanf("%f",&twenty);
     
   
   m = (one + two + three + four + five + six + seven + eight + nine + ten + eleven + twelve + thirteen + fourteen + fifteen + sixteen + seventeen + eighteen + nineteen + twenty)/20;
      
  printf("The mean for these values is: %f\n", m);
    
     }
     
      else {
	printf("Not a valid command.\n");
      }
  
  
  
  printf("1 - Mean\n2 - Median\n3 - Mode\n4 - All three\nChoice : ");
  scanf("%d",&instr);
 
      }
      else {
	printf("Not a valid command.\n");
      }
    }
  }
