Thread: Help. execution stopped everytime i try to add data from scanf

this is a syntax i've been trying to run. apparently it stopped as i entered the first value.

can anyone check why this is happening?
this is the value i am trying to key in

Initial House Cost
67,000
62,000
75,000

Annual Fuel Cost
2,300
2,500
1,850

Tax Rate
0.025
0.025
0.020


my syntax are as below

Code:

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


int main(void)


{


	float houseInt1 , houseInt2 , houseInt3 ;
	float fuelAnnual1 , fuelAnnual2 , fuelAnnual3;
	float taxRate1 , taxRate2 ,taxRate3;
	float total1 , total2 , total3;
	
			printf("Enter the initial house cost for house number 1");
			scanf("%f",houseInt1);
			
			printf("Enter the Annual Fuel Cost for house number 1");
			scanf("%f",fuelAnnual1);
			
			printf("Enter the taxRate for house number 1");
			scanf("%f",taxRate1);


			printf("Enter the initial house cost for house number 2");
			scanf("%f",houseInt2);
			
			printf("Enter the Annual Fuel Cost for house number 2");
			scanf("%f",fuelAnnual2);
			
			printf("Enter the taxRate for house number 2");
			scanf("%f",taxRate2);
			
			printf("Enter the initial house cost for house number 3");
			scanf("%f",houseInt3);
			
			printf("Enter the Annual Fuel Cost for house number 3");
			scanf("%f",fuelAnnual3);
			
			printf("Enter the taxRate for house number 3");
			scanf("%f",taxRate3);
			
		total1 = houseInt1 + fuelAnnual1*5 + houseInt1*taxRate1*5;
		total2 = houseInt2 + fuelAnnual2*5 + houseInt2*taxRate2*5;
		total3 = houseInt3 + fuelAnnual3*5 + houseInt1*taxRate3*5;


			
	printf("total cost of a house after a five-year period");
	printf("house 1 = %f  house 2 = %f  house 3 = %f", total1, total2, total3 );
	
	if (total1<=total2 && total1<=total3)
		printf("best buy is house number 1 = %f", total1);
	else if(total2<= total1 && total2<=total3)
		printf("best buy is house number 2 = %f", total2);
	else
		printf("best buy is house number 3 = %f", total3);	
	return 0;	
}

i'm stuck i don't know what to do....

All those errors you got about how scanf required pointers instead of values should be giving you a hint about what you need to fix (to wit: all your scanf calls need pointers instead of values).

omg.. thank you so much...

thank you.. gosh you are right. i should have seen it...

thank you for the comments, i am using devc++ compiler i didn't set anything but the compiler didn't even give me any warning... i'll try to search what went wrong to the compiler

It's the maintained fork of dev-c++, and comes with an updated version of gcc.

Then you normally do something like
project->settings->compiler
and you find either check boxes (or an edit box) where you enable all the additional warnings.

thank you Salem the warning is working now.
