In this article, we are going to **write a c program to find Average of n Odd and Even Numbers.**

We will make this program in the following way -:

- C Program to Find the Average of n Odd and Even Numbers
**Using For Loop** - C Program to Find the Average of n Odd and Even Numbers
**Using While Loop** - C Program to Find the Average of n Odd and Even Numbers
**Using Do While Loop** - C Program to Find the Average of n Odd and Even Numbers
**Using Function**

To make this program, we will use the following concept -:

If you do not know about these topics well, then you may not understand this program, so you should know about them in detail from the link given above.

Now without wasting time let’s start programming.

## C Program to Find Average of n Odd and Even Numbers Using **For Loop **

**Program** -:

```
//C Program to Find the average of n odd Numbers in a Given Range (Using For Loop)
#include<stdio.h>
void main()
{
//Declaring Variable
int num1, num2, i, sum = 0,count = 0;
float avg;
//Input Number
printf("Enter Starting Number\n");
scanf("%d",&num1);
printf("Enter Ending Number\n");
scanf("%d",&num2);
for(i=num1;i<=num2;i++)
{ if(i%2==0)
{
continue ;
}
else
{
sum = sum + i;
count++;
}
}
avg = (float)sum/count;
printf("\nAverage of odd Numbers in Given Range : %f", avg);
}
```

**Output **-:

```
Enter Starting Number
1
Enter Ending Number
10
Average of odd Numbers in Given Range : 5
```

## C Program to Find the Average of n Odd and Even Numbers Using **While Loop **

**Program** -:

```
//C Program to Find the average of n odd Numbers in a Given Range Using While Loop
#include<stdio.h>
void main()
{
//Declaring Variable
int num1, num2, i, sum = 0,count = 0;
float avg;
//Input Number
printf("Enter Starting Number\n");
scanf("%d",&num1);
printf("Enter Ending Number\n");
scanf("%d",&num2);
while(num1<=num2)
{ if(num1%2 != 0)
{
sum = sum + num1;
count++;
}
num1++;
}
avg = (float)sum/count;
printf("\nAverage of odd Numbers in Given Range : %f", avg);
}
```

**Output **-:

```
Enter Starting Number
1
Enter Ending Number
20
Average of odd Numbers in Given Range : 10.000000
```

## C Program to Find the Average of n Odd and Even Numbers Using Do **While Loop **

**Program** -:

```
//C Program to Find the average of n odd Numbers in a Given Range Using Do While Loop
#include<stdio.h>
void main()
{
//Declaring Variable
int num1, num2, i, sum = 0,count = 0;
float avg;
//Input Number
printf("Enter Starting Number\n");
scanf("%d",&num1);
printf("Enter Ending Number\n");
scanf("%d",&num2);
do
{ if(num1%2 != 0)
{
sum = sum + num1;
count++;
}
num1++;
}while(num1<=num2);
avg = (float)sum/count;
printf("\nAverage of odd Numbers in Given Range : %f", avg);
}
```

**Output **-:

```
Enter Starting Number
1
Enter Ending Number
10
Average of odd Numbers in Given Range : 5.000000
```

## C Program to Find the Average of n Odd and Even Numbers Using Function

**Program** -:

```
//C Program to Find the Sum of n odd Numbers in a Given Range (Using while Loop)
#include<stdio.h>
int average(int , int);
void main()
{
//Declaring Variable
int num1, num2, avg ;
//Input Number
printf("Enter Starting Number\n");
scanf("%d",&num1);
printf("Enter Ending Number\n");
scanf("%d",&num2);
avg = average(num1, num2);
printf("\Average of odd Numbers in Given Range : %d", avg);
}
int average(int num1, int num2)
{
int sum = 0, count = 0;
do
{
if(num1%2 != 0)
{
sum = sum + num1;
count++;
}
num1++;
}while(num1<=num2);
return (sum/count);
}
```

**Output **-:

```
Enter Starting Number
11
Enter Ending Number
20
Average of odd Numbers in Given Range : 15
```
