2. Reprogram the coding above to calculate

3. Total

5. Input 12 number

6. Calculate total

7. Calculate Average

8. Exercise 3: Compile and run the program below#include<stdio.h><br />#include<conio.h><br />char matrik[20],nama[50];<br />float kiratotal(float x, float y, float z){<br /> float a;<br /> a=x+y+z;<br /> return a;<br /> }<br />float kirapurata(float b){<br /> <br /> return (b/3);<br /> }<br /> <br /> <br />int display (float total, float average){<br />printf(quot;
