# C Program to Find the Sum and Average of Numbers Using Do-While Loop

In this program we will find the sum and average of the given numbers using do-while loop which allows to calculate the sum and average.
Do-while loop is a looping condition where statements are executed continuously until the condition validates and test the condition after having executed the statements within the loop.
This means that do-while would execute its statements at least once, even if the condition fails for the first time.
Scanf() command is used here to allow enter the numbers and sum=sum+num; to sum the numbers within do-while loop.

## C Program to Find the Sum and Average of Numbers Using Do-While Loop

Steps:

1. Declare two integers i and n and also initialize i with 0.
2. Declare three floats sum, avg and num and initialize sum with 0.
3. Print the message on the screen to enter how many numbers want to find sum.
4. Use do-while loop to insert the numbers calculate the sum and average.

Code:

```#include<stdio.h>
#include<conio.h>

void main()
{

int i=0,n;
float sum, avg, num;

clrscr();

sum=0;

printf("How many numbers you want to find sum and averagen");
scanf("%d",&n);

printf("Enter the numbersn");

do{
scanf("%f", &num);
sum=sum+num;
i++;
}

while (i<n);

avg=sum/n;

printf("Sum=%fn", sum);
printf("Average=%fn", avg);
getch();
}

```
