C program to generate an electricity bill

CServer Side ProgrammingProgramming

Based on the units consumed by the user, the electricity bill is generated. If number of units consumed are more then, the rate of a unit charge will also increase.

The logic applied if minimum units are consumed by the user is as follows −

if (units < 50){
   amt = units * 3.50;
   unitcharg = 25;
}

The logic applied if units are in between 50 to 100 is given below −

else if (units <= 100){
   amt = 130 + ((units - 50 ) * 4.25);
   unitcharg = 35;
}

The logic applied if units are in between 100 to 200 is as stated below −

else if (units <= 200){
   amt = 130 + 162.50 + ((units - 100 ) * 5.26);
   unitcharg = 45;
}

The logic applied if number of units are more than 200 is mentioned below −

amt = 130 + 162.50 + 526 + ((units - 200 ) * 7.75);
unitcharg = 55;

Therefore, the final amount will be generated with the logic as given below −

total= amt+ unitcharg;

Example

Following is the C Program to generate an electricity bill −

 Live Demo

#include <stdio.h>
int main(){
   int units;
   float amt, unitcharg, total;
   printf(" Enter no of units consumed : ");
   scanf("%d", &units);
   if (units < 50){
      amt = units * 3.50;
      unitcharg = 25;
   }else if (units <= 100){
      amt = 130 + ((units - 50 ) * 4.25);
      unitcharg = 35;
   }else if (units <= 200){
      amt = 130 + 162.50 + ((units - 100 ) * 5.26);
      unitcharg = 45;
   }else{
      amt = 130 + 162.50 + 526 + ((units - 200 ) * 7.75);
      unitcharg = 55;
   }
   total= amt+ unitcharg;
   printf("electricity bill = %.2f", total);
   return 0;
}

Output

When the above program is executed, it produces the following result −

Enter no of units consumed: 280
electricity bill = 1493.50
