WRITE A C PROGRAM:

//Header files
#include<stdio.h>
#include<conio.h>
 
void main()
{
//Program variables
int b[10],j,sum=0;
float av;
 
clrscr(); //Function to clear previous output
 
for(j=1;j<=10;j++) //looping statement
{
printf("ENTER THE %d NUMBER:--" ,&j); //Display function
scanf("%d",&b[j] );  //Getting input function
}
for(j=1;j<=10;j++)
printf("\nthe numbers are %d",b[j]);
for(j=1;j<=10;j++)
sum=sum+b[i];
printf("\n THE SUM OF  NUMBERS ARE: %f",sum);
av=sum/10;
printf("\n THE AVERAGE OF  NUMBERS R:%2.2f",av);
getch();
