Thread: Program help

Hi. I am a beginner at C Programming. I'm really in the dark about a lot of stuff in this department, so I thought maybe I could get some help from on here.

I have an assignment I have to do for class, and it's just mind-boggling to my little brain So, hopefully someone can give me some advice and assistance.

Okay, here's what I have to do:

Objective
The objective of this problem is to develop a Fine Calculator program that will:
Input a driver’s speed as measured by traffic patrol.
Determine if a speeding ticket is to be issued and if so, determine the amount of the fine.
Assume fine amount 0 when there is no speed violation.
Output the fine.
Background
For this lab, make the following assumptions:
The fine for speeding in a 45 MPH zone is $10 for every mile per hour over the speed limit for speeds from 46 to 55 MPH.
It is $15 for every additional mile per hour between 56 and 65 MPH.
It is $20 for every additional mile per hour over 65 MPH.
For example, the fine for driving 57 MPH is $100 for the fast 10 MPH plus $30 for the 2 MPH in excess of 55 MPH, for a total of $130.


Now, I know I need to first have a scan function that will scan for the user's input. And should have an "int" for the speed? I was wondering how I would do this for the if statement...since I need the if statement to say "if it's in between two numbers" would it be like:

if (speed>45 && speed<55); ?

and any ideas on what I could do to make it so it would add 10 dollars for each mile gone over the 45.


Any help would be greatly appreciated.
I just really want to learn how to do this.

This is what I've got so far...

Code:

#include <stdio.h>

int main (void){

//declarations
int speed;
int fine;
int46;
int56;
int65;
//give the user information on what to do
printf("Please input the speed of the vehicle:\n");
//get input

scanf("%d",&speed);
if(speed<46 && speed>56){
fine=(
}
return 0;
}

any suggestions on the math for the fine=(

I think if I could figure that out, I could get the rest done

i did something like this but i think its bad programing maybe there is another way of doing it still didnt finish it

Code:

 

#include<stdio.h>
#include<stdlib.h>
#include<conio.h>

main(){
       
       int speed;
       int add;
       int t;
       printf("\n enter the speed  ");
       scanf("\n%i",&speed);
       
       if(speed<=45)
       {
                 
       }
       else if (speed>=46&&speed<=55)
       {
        if(speed==46)
       {
        add=10;
        printf("$%i",add);
        }
       if(speed==47)        
       {
        t=20;
       printf("$%i",t);
       }
       if(speed==48)        
       {
        t=30;
       printf("$%i",t);
       }
       if(speed==49)       
       {
        t=40;
       printf("$%i",t);
       }
       
        if(speed==50)       
       {
        t=50;
       printf("$%i",t);
       }
        if(speed==51)       
       {
        t=60;
       printf("$%i",t);
       }
        if(speed==52)       
       {
        t=70;
       printf("$%i",t);
       }
        if(speed==53)       
       {
        t=80;
       printf("$%i",t);
       }
        if(speed==54)       
       {
        t=90;
       printf("$%i",t);
       }
        if(speed==55)       
       {
        t=100;
       printf("total speed$%i",t);
       }
       
       
       }
else if (speed>=56&&speed<=65)
 {
     {
           if(speed==56)
           {

           }
           if(speed==60)       
           {

RE: quazah can you explain what your code does. i try to follow your code but iam not sure
