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

Here, i will show you algorithm and programs to find average of 3 and number in c programs; is as follow:

- Algorithm of 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 of find the average of three or 5 numbers

- Step 1: Start Program
- Step 2: Read the three or five numbers from the user.
- Step 3: Declared a variable “Avg”.
- Step 4: Find average of 3 or 5 numbers using the following 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 result 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 result of the above c program; as follows:**

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