Re: Post ur C/C++ Programs Here

Here's a program to calculate the computer sales man salary. Base salary, bonus rate and commission are fixed. Input of price per system and number of systems sold is from user.

Code:

#include<stdio.h>
#define BASE_SAL 2000.0
#define BONUS 200.0
#define COMMISSION 0.02

//Compiled on linux using geany

int main()
{
    int n;
    float bonus, commission, price;
    float gross_sal;
    printf("\nInput the number of systems sold  ",n);
    scanf("%d",&n);
    printf("\nInput the price of each computer  ",price);
    scanf("%f",&price);
    bonus=BONUS*n;
    commission=COMMISSION*price*n;
    gross_sal=BASE_SAL+bonus+commission;
    printf("Base salary is %f\nBonus is %f\nCommission is %f\nGross salary is %f"
    ,BASE_SAL,commission,gross_sal);
}

Gross salary is coming out to be wrong but I don't know why. Please tell if you realize that.

Re: Post ur C/C++ Programs Here

You missed a variable in your printf() statement. The bonus variable I suppose. Or BONUS.

Code:

#include<stdio.h>
#define BASE_SAL 2000.0
#define BONUS 200.0
#define COMMISSION 0.02

//Compiled on linux using geany

int main()
{
    int n;
    float bonus, commission, price;
    float gross_sal;
    printf("\nInput the number of systems sold  ",n);
    scanf("%d",&n);
    printf("\nInput the price of each computer  ",price);
    scanf("%f",&price);
    bonus=BONUS*n;
    commission=COMMISSION*price*n;
    gross_sal=BASE_SAL+bonus+commission;
    printf("Base salary is %f\nBonus is %f\nCommission is %f\nGross salary is %f\n"
    ,BASE_SAL,[B]bonus[/B],commission,gross_sal);
}

Code For Sudoku:

Here is the code to solve Sudoku which i wrote in C

It's bit-lenghty but it can solve all difficulty levels

here is the input format to be given at the command prompt
--->./a.out

11 5
12 4

51 3
55 2
61 7
66 5
68 3

-1

0-80 is the grid numbers

I could help you do your class 12 project, but for a reasonable sum.

Is that okay with you or are you gonna learn more than #include(s) ?

there are plenty of sites which offer you what you need which you can get on google, which spoil your academics. Its a project. This is the time for you to learn.
