Code for understanding:
#include<stdio.h>
#include<conio.h>

int main()
{
float a; // Making variable "a" to store consumed units
printf("Please Enter consumed Units: ");
scanf("%f",&a); // Storing input units (any number) in variable "a"
if (a<=200) // If unites are less than or equal to 200 then
printf("\n\nTotal units price = %2.2f:\n\n",a*4); //What number will be in variable "a" will be
multiply with 4 and result will be shown

else if (a<=400) // If units are less than or equal to 300 then
printf("\n\nTotal units price = %2.f:\n\n",(a-200)*6+200*4); //200 units will be minus from
variable "a" and remaining
units will be multiplied  with 6,
200 units will be multiplied with
4 and the result will be added with
previous result  according to
DMAS
else if (a>400) // If units are greater than 400 then
printf("\n\nTotal units price = %2.f:\n\n",(a-400)*8+200*4+200*6); //400 units will be minus
from variable "a"
and remaining units will be
multiplied with 8, 200 units
will be multiplied with
4,  200 units will be
multiplied with 6 and all
results will be sum
according to DMAS
