# C Program to Find Average of 3, 5 Number

C program to find the average of 3 and 5 numbers; In this tutorial, you will learn how to find the average of 3 and 5 numbers in c.

## Programs to Find Average of 3, 5 Number in C

Use the following algorithm to write a program to calculate average of n(3,4,5,etc) numbers in c:

• Algorithm to find the average of three or five numbers
• C Program to Find Average of 3 Number
• C Program to Find Average of 5 Number

### Algorithm to find the average of three or 5 numbers

• Step 1: Start
• Step 2: Read the three or five numbers from the user.
• Step 3: Declared a variable “Avg”.
• Step 4: Calculate the average of 3 or 5 numbers using the followig formulas:
• avg = (a+b+c)/3;
• avg = (a+b+c+e+f)/3;
• Step 5:Display “sum ” and “Avg”.
• Step 6:End.

### C Program to Find Average of 3 Number

```#include<stdio.h>

int main()

{

float a,b,c,avg;

printf("Please enter 3 numbers ");

scanf("%f%f%f", &a, &b, &c);

avg=(a+b+c)/3;

printf("\nAverage is  %f",avg);

return 0;

}```

The output of the above c program; as follows:

```Please enter 3 numbers 10 20 30
Average is  20.000000```

### C Program to Find Average of 5 Number

```#include<stdio.h>

int main() {

float a, b, c, d, e, s, avg;

printf("Please Enter 5 Numbers :");
scanf("%f%f%f%f%f", &a, &b, &c, &d, &e);

s = a + b + c + d + e;

avg = s / 5;

printf("\nThe Average is :%f", avg);

return 0;
}```

The output of the above c program; as follows:

```Please Enter 5 Numbers :10 20 30 40 50
The Average is :30.000000```
