<u>Answer:</u>
<u><em>Algorithm:
</em></u>
<em>Step 1: </em><em>Begin
</em>
<em>Step 2: </em><em>Obtain the inputs – all the three integers
</em>
<em>Step 3: </em><em>Calculate product using the formula “a*b*c”
</em>
<em>Step 4: </em><em>Calculate sum and then with the help of sum calculate the average
</em>
<em>Step 5: </em><em>Print the value of product and average
</em>
<em>Step 6: </em><em>End
</em>
<u>Explanation:</u>
<u><em>Program:
</em></u>
<em>#include<stdio.h>
</em>
<em>int main () {
</em>
<em> int a, b, c;
</em>
<em> printf(""Enter three numbers: "");
</em>
<em> scanf(""%d %d %d"", &a, &b, &c);
</em>
<em> int sum = a + b + c;
</em>
<em> int product = a * b * c;
</em>
<em> float avg = sum / 3.0;
</em>
<em> printf(“Product = %d”, product”); </em>
<em> printf(""Sum = %d, Average = %f"", sum, avg);
</em>
<em> return 0;
</em>
<em>}
</em>
