Thread: Newbie to C

Hi,
I just wanted to know if someone could help me with if and else statements.
Im pretty new to C programming,but im finding some aspects of if and else statements a bit difficult. I'm having a problem with this assignment.

Write a program which helps an insurance broker determine insurance premiums according to the following table.

Car Age Engine Size Convictions Message
>=15 >=2000 >=3 Policy loaded by 45%
>=15 >=2000 < 3 Policy loaded by 20%
<15 < 2000 < 3 no loading


The program first needs to aquire the age of the car, the engine size and the number of convictions from the user, and then it should print out the appropriate message.

The problem im having is how to set the program up, in terms of if and else statements, and how to write the program so it gets all the information from the user, and then works out which policy they get if any. If it is possible could someone help me with another similiar program, so when I understand it, I can do this write this program myself.

Any help with be much appreciated.

Hi Matsp,
Sorry if it sounded like I wanted you to do my work, I didn't mean it to.
Here is my code so far,

Code:

#include<stdio.h>

void main()
{
	int CarAge, EngineSize, Convictions, Message;
	printf("Please enter the age of the car ");
	scanf("&#37;i", &CarAge);
	printf("Please enter the size of the engine ");
	scanf("%i", &EngineSize);
	printf("Please enter the any convictions ");
	scanf("%i", &Convictions);
	
	if (CarAge >= 15)
	else 
	    printf("No Loading");

    if (EngineSize >= 2000)
	else 
	    printf("No Loading");

	if (Convictions >= 3)
        printf("policy loaded by 45%");
	else if (Convictions < 3)
	    printf("policy loaded by 40%");
	else 
	    printf("No Loading");
	
}

Problem im having is what do I type into the 'if' part, so if the CarAge is valid, it will store it
and move onto the Engine Size, and then if the Engine Size is valid, it will store it and move it onto the Convictions. Then if conviction is valid it should print out the appropriate message.

Thanks for helping.

Hi matsp

Is this what you mean about adding those curly brackets

Code:

#include<stdio.h>

void main()
{
	int CarAge, EngineSize, Convictions, Message;
	printf("Please enter the age of the car ");
	scanf("%i", &CarAge);
	printf("Please enter the size of the engine ");
	scanf("%i", &EngineSize);
	printf("Please enter the any convictions ");
	scanf("%i", &Convictions);
	
	{
	if (CarAge >= 15)
	else 
	    printf("No Loading");
	}

	{
    if (EngineSize >= 2000)
	else 
	    printf("No Loading");
	}

	{
	if (Convictions >= 3)
        printf("policy loaded by 45%");
	else if (Convictions < 3)
	    printf("policy loaded by 40%");
	else 
	    printf("No Loading");

	}

	
}

At the moment when I try to run the program I get these two errors:

1>.\workshop3.cpp(15) : error C2181: illegal else without matching if
1>.\workshop3.cpp(21) : error C2181: illegal else without matching if


The things is what do I have to write so it checks that the CarAge value, if it is valid it then moves on the Engine Size, if it isnt it gives you the error message

Thanks for you help.
