## 10. WAP to check whether the given number is prime or composite.
416+

### Program
418+

```c
420+
//WAP to check whether the given number is prime or composite.
421+
422+
#include <stdio.h>
423+
424+
int main() {
425+
426+
int n, i, flag = 0;
427+
printf("Enter a positive integer: ");
428+
scanf("%d", &n);
429+
430+
// 0 and 1 are not prime numbers
431+
// change flag to 1 for non-prime number
432+
if (n == 0 || n == 1)
433+
flag = 1;
434+
435+
for (i = 2; i <= n / 2; ++i) {
436+
437+
// if n is divisible by i, then n is not prime
438+
// change flag to 1 for non-prime number
439+
if (n % i == 0) {
440+
flag = 1;
441+
break;
442+
}
443+
}
444+
445+
// flag is 0 for prime numbers
446+
if (flag == 0)
447+
printf("%d is a prime number.", n);
448+
else
449+
printf("%d is not a prime number.", n);
450+
451+
return 0;
452+
}
453+
```
454+
This C program checks whether the given number is prime or composite.
455+
456+
This program takes an integer as input from the user.
457+
If the number is 0 or 1 then the flag is assigned 1.
458+
Then i is initialized as 2 and then i assigned as the numbers in range (2,n/2).
459+
If the input goes through a loop where if the integer is divisible by 'i' then
460+
the flag is assigned 1 else the flag is assigned to 0. Finally the program checks
461+
the value of flag. I the flag is 1 the it prints the integer is prime while it
462+
prints the integer is not prime if the flag is 0.
463+
464+
For example, the input is seven then this program prints "7 is a prime number".

## 1. WAP to build a simple electricity bill generator.

46+
}
47+
48+
//you can automate the bill no, date and sc no for advancement
49+
printf("~~~NEPAL ELECTRICITY AUTHORITY~~~\n");
50+
printf("-----------------------------------\n");
51+
printf("\tELECTRICITY BILL\n");
52+
printf("-----------------------------------\n\n");
53+
printf("BILL NO:\t843948394\n");
54+
printf("BILL DATE:\t2079/12/12\n");
55+
printf("BRANCH:\t\tDAMAK\n");
56+
printf("-----------------------------------\n");
57+
printf("SC NO:\t\t309.11.012A\n");
58+
printf("BILL NO:\t843948394\n");
59+
printf("TOTAL UNITS:\t%d\n",units);
60+
printf("TOTAL AMOUNT:\tRS.%.3f\n",price);
61+
printf("-----------------------------------\n");
62+
printf("-----------------------------------\n");
63+
return 0;
64+
}
65+
```
66+
67+
This C program allows a user to input total electricity units and generate
68+
the bill in proper format.
69+
70+
The basic logic of this C program is to take an integer 'units' as input
71+
from the user and the if else ladder checks suitable case for the units.
72+
If the unit is less than or equals to 20 units, then the rate is Rs.4 per
73+
unit which is assigned to 'price'. But if the units exceeds 20 and less
74+
than or equals to 50 then the price of 20 units is added to the price of
75+
remaining units. Same case continues untill 250 units. If the unit is more
76+
than 250 then the total sum price of 250 units is added to price of remaining
77+
units. After 250 units the rate is Rs.12.5 per unit even if the unit is way
78+
heigher.
79+
80+
Finally the bill is generated through a self written format which includes
81+
Bill no, Bill date, Total units, Total amount,etc.
82+
83+
For example, if the user input is 40 then the bill is generated for 40 units.
