Answer 1

#include<stdio.h>

int main()

{

// declare variable

float num1, num2, num3;

float sum, avg;

// take inputs

printf("Enter three Numbers: ");

scanf("%f %f %f",&num1, &num2, &num3);

// calculate sum

sum = num1 + num2 + num3;

// calculate average

avg = sum / 3;

// display entered numbers

printf("Entered numbers are: %.2f, %.2f and %.2f\n",

num1, num2, num3);

// display sum and average

printf("Sum=%.2f\n", sum);

printf("Average=%.2f\n",avg );

return 0;

Output:-

Enter three Numbers: 10 20 30

Entered numbers are: 10.00, 20.00 and 30.00

Sum=60.00

Average=20.00

Enter three Numbers: 1.9 2.5 8.16

Entered numbers are: 1.90, 2.50 and 8.16

Sum=12.56

Average=4.19
