## C Program to Find Average of n Natural Numbers Using **For Loop **

**Algorithm **-:

- Program Start
- Variable Declaration (i,n,sum)
- Input a Number from the User
- Calculating Sum of n Naturals Numbers
- Calculating Average of n Naturals Numbers
- Displaying the Average of n Naturals Numbers
- Program End

**Program** -:

```
//C Program to Find the Average of n Natural Numbers Using For loop
#include<stdio.h>
int main()
{
//Declaring Variable
int n, i, sum = 0, count = 0;
//Input Number
printf("Enter a Number\n");
scanf("%d",&n);
for(i=1;i<=n;i++)
{
sum = sum + i;
count++;
}
printf("\nAverage of first %d Natural Numbers = %d",n, sum/count);
return 0;
}
```

**Output **-:

```
Enter a Number
5
Average of first 5 Natural Numbers = 3
```

## C Program to Find the Average of n Natural Numbers Using **While Loop **

**Program** -:

```
//C Program to Find the Average of n Natural Numbers Using While loop
#include<stdio.h>
void main()
{
int n, i=1, sum = 0,count =0 ;
printf("Enter a Number\n");
scanf("%d",&n);
while(i<=n)
{
sum = sum + i;
count++;
i++;
}
printf("\nAverage of first %d Natural Numbers = %d",n, sum/count);
}
```

**Output **-:

```
Enter a Number
10
Average of first 10 natural number = 5
```

## C Program to Find the Average of n Natural Numbers Using Do **While Loop **

**Program** -:

```
//C Program to Find the Average of n Natural Numbers Using Do While Loop
#include<stdio.h>
int main()
{
int n, i=1, sum = 0, count = 0;
printf("Enter A Number to Calculate Average\n");
scanf("%d",&n);
do
{
sum = sum + i;
count++;
i++;
}while(i<=n);
printf("\nAverage of first %d Natural Numbers = %d",n,sum/count);
return 0;
}
```

**Output **-:

```
Enter a number to calculate average
10
Average of first 10 Natural Number = 5
```

## C Program to Find the Average of n Natural Numbers Using Function

**Program** -:

```
//C Program to Find the Average of n Natural Numbers Using function
#include<stdio.h>
int average(int);
void main()
{
int n, i=1, avg;
printf("Enter A Number\n");
scanf("%d",&n);
avg=average(n);
printf("\nAverage of first %d Natural Numbers = %d",n,avg);
}
int average(int n)
{
int i,sum=0,count =0;
for(i=1;i<=n;i++)
{
sum = sum + i;
count++;
}
return (sum/count);
}
```

**Output **-:

```
Enter a number
20
Average of first 20 Natural Numbers = 10
```

## C Program to Find the Average of n Natural Numbers Using Recursion

**Program** -:

```
//C Program to Find the Average of n Natural Numbers Using Recursion
#include<stdio.h>
int sum(int);
int average(int, int);
void main()
{
int n, s,avg;
printf("Enter A Number\n");
scanf("%d",&n);
s=sum(n);
avg = average(s, n);
printf("\nAverage of first %d Natural Numbers = %d",n,avg);
}
int sum(int n)
{
int s=0;
if(n==1)
return (n);
s = n + sum(n-1);
return (s);
}
int average(int s, int n)
{
return (s/n);
}
```

**Output **-:

```
Enter a Number
100
Average of first 100 Natural Numbers = 50
```
