int i,n,sum=0;

float avg;

printf("Input the 10 numbers : \n");

for (i=1;i<=10;i++)

{

printf("Number-%d :",i);

scanf("%d",&n);

sum +=n;

}

avg=sum/10.0;

printf("The sum of 10 no is : %d\nThe Average is : %f\n",sum,avg);

}

hope it is useful for u

Answer 2

Below are the program for the above problem in C language is listed below:

Explanation:

#include <stdio.h>// header file inclusion.

int main() // main function.

{

   int i=0, sum=0,number; // variable declaration which store integer value.

   float avg=0; //  variable declaration for decimal value.

   while(i<10) // while loop which executes its body on 10 times.

   {

       scanf("%d",&number); // input statement to take the input.

       sum=sum+number; // add the every input number.

       i++; // increment for while loop.

   }

     avg=sum/10; // count the average of inputted value.

    printf("Sum=%d Avg=%f",sum,avg); // print the sum and average value.

   return 0; // return the statement.

}

Output:

• If the user enters 1,2,3,4,5,6,7,8,9,10 then the output is "Sum=55 Avg=5.000000"

Code explanation:

• Here in this program, there is a while loop which executes his body for the 10 times to take the 10 value from the user
• The value is get added to the Sum variable every time.
• Then the average is calculated by the help of Sum divided by 10.
• Then the average and sum is displayed by the help of prinf function
