Thread: Having Trouble with a nested if else if statement.

I am working on a project for school and I am having difficulty getting this section of code to give the desired output. Can someone give me alittle guidance? No matter what value I input I get the first printf statement as a result.

if (n<5.0)
printf("There will be little or no damage with this earthquake.\n\n", n);

else if (n>=5.0 && n<5.5)
printf("There will be some damage with this earthquake.\n\n", n);

else if (n>=5.5 && n<6.5)
printf("There will be serious damage with this earthquake: walls may crack or fall.\n\n", n);

else if (n>=6.5 && n<7.5)
printf("Disastrous results will occur with this earthquake: houses and buildings may collapse.\n\n", n);

else
printf("Catastrophic results will occur with this earthquake: most buildings will be destroyed.\n\n", n);

No matter what value I input I get the first printf statement as a result.

Usually that symptom indicates you have a semicolon after your if-statement. Alternatively, you should check that you are assigning something to n.

Here is what I have written so far, everything is compiling fine. Thanks for the quick response.

Code:

#include<stdio.h>

/* Function prototypes*/
void instruct_user(void);

int
main(void)
{
	double n; /* Represents the number registered on Richter Scale */

	/* Display user instructions.*/
	instruct_user();

	/* Get user input*/
	printf("Enter the number registered on the Richter scale and press return> ");
	scanf("%1f", &n);
	
	/*The decision making process based on a Multiple-Alternative Decision order of conditions*/
	/*A switch statement could not be used when inputing type double there for if else is more appropriate.*/

	if (n<5.0) 
		printf("There will be little or no damage with this earthquake.\n\n", n);

	else if (n>=5.0 && n<5.5)
			printf("There will be some damage with this earthquake.\n\n", n);

	else if (n>=5.5 && n<6.5)
			printf("There will be serious damage with this earthquake: walls may crack or fall.\n\n", n);

	else if (n>=6.5 && n<7.5)
			printf("Disastrous results will occur with this earthquake: houses and buildings may collapse.\n\n", n);

	else 
			printf("Catastrophic results will occur with this earthquake: most buildings will be destroyed.\n\n", n);
	
	return (0);
}
/* Displays user instructions*/
void
instruct_user(void)
{
	printf("This program will take input from the user and provide the user with the affects\n");
	printf("of an Earthquake based on it's Richter scale.\n\n");
}

Code:

%lf

and

Code:

%1f

are not the same thing.

Thanks so much I have been looking at this for a couple of hours, as I am a rookie I guess this would classify as a rookie mistake
Thanks again
