# C Program to Read 10 Numbers and Find their Sum and Average

Write a C program to read 10 numbers and find their sum and average using for loop. In this example, for loop iterate from 1 to 10, add each number to the sum to find the sum of 10 numbers. Next, we calculate the average.

```#include <stdio.h>

int main()
{
int num, sum = 0;
float avg;

for(int i = 1; i <= 10; i++)
{
printf("Number %d = ", i);
scanf("%d", &num);
sum = sum + num;
}

avg = sum / 10;

printf("\nThe Sum of 10 Numbers     = %d", sum);
printf("\nThe Average of 10 Numbers = %.2f\n", avg);
}```

This C program reads 10 numbers from the user input and calculates their sum and average using a while loop.

```#include <stdio.h>

int main()
{
int num, i, sum = 0;
float avg;

i = 1;

while(i <= 10)
{
printf("Number %d = ", i);
scanf("%d", &num);
sum = sum + num;
i++;
}

avg = (float)sum / 10.0;

printf("\nThe Sum of 10 Numbers     = %d", sum);
printf("\nThe Average of 10 Numbers = %.2f\n", avg);
}```
``````Please Enter the 10 Numbers
Number 1 = 22
Number 2 = 33
Number 3 = 44
Number 4 = 55
Number 5 = 67
Number 6 = 89
Number 7 = 123
Number 8 = 234
Number 9 = 543
Number 10 = 199

The Sum of 10 Numbers     = 1409
The Average of 10 Numbers = 140.90``````
