How do you calculate water bill from C programming?

Answer 1

#include<iostream>

using namespace std;

#include<conio.h>

void main()

{

char m[100];

int units[100],i,j,n;

float x,tb;

cout<<"enter the total number of bills to be calculate:\n";

cin>>n;

for(i=1;i<=n;i++)

{

cout<<"\nenter the name \n:==>";

cin>>m;

for(i=0;i<n;i++)

{

cout<<"\nenter the total units consumed \n:==>";

cin>>units[i];

}

}

if(units[i]<=100)

{

x=units[i]*0.6;

tb=50+x;

if(tb>300)

{

tb=0.15*tb+tb;

}

cout<<"\ncalculated bill:==>";

cout<<m<<tb;

}

else if(units[i]>100 && units[i]<=300)

{

tb=100*0.6+(units[i]-100)*0.8+50;

if(tb>300)

{

tb=0.15*tb+tb;

}

cout<<"\ncalculated bill:==>";

cout<<m<<tb;

}

else if(units[i]>300)

{

tb=100*0.6+200*0.8+(units[i]-300)*0.9+50;

if(tb>300)

{

tb=0.15*tb+tb;

}

cout<<"\ncalculated bill:==>";

cout<<m<<tb;

}

getch();

}
