1. ## Temperature conversion...

Hi, I'm new at C programming, and I'm following the HowStuffWorks.com C programming tutorial/guide until I get some books- it has nice examples and lets you experiment. Anyways, I'm working on a temperature conversion program- a basic loop project. I'm trying to convert Fahrenheit to Celcius with user-inputted starting temp, ending temp, and increment value. Problem is, IT KEEPS REPEATING. I've spent an hour trying to figure out why, but i can't find the cause of it all. So here's the code. Thanks

Code:
```#include <stdio.h>

int main()
{

float a, b, c, d;
printf("Enter a value for the starting temperature in Fahrenheit:");
scanf("%f", b);
printf("Enter a value for the ending temperature in Fahrenheit:");
scanf("%f", c);
printf("Enter a value for the temperature increment value in Fahrenheit:");
scanf("%f", d);
a = b;
printf("This is a Fahrenheit to Celcius Conversion Table!");
while (a <= c)
{
if ((a > 98.6) && (a < (a + d)))
{

printf("%f degrees F = %f degrees C\n",
98.6, (98.6 - 32.0) * 5.0 / 9.0);

}

printf("%f degrees F = %f degrees C\n",
a, (a - 32.0) * 5.0 / 9.0);
a = (a + d);

}

return 0;

}```

2. You had a few minor errors that I fixed, this code works fine for me. You'll just want to format the output on your floats to whatever way you feel nessassary. I set the precision to two places.

Code:
```#include <stdio.h>

int main()
{

float a, b, c, d;
printf("Enter a value for the starting temperature in Fahrenheit:");
scanf("%f", &b);     // You had b, should be &b
printf("Enter a value for the ending temperature in Fahrenheit:");
scanf("%f", &c);     // You had c, should be &c
printf("Enter a value for the temperature increment value in Fahrenheit:");
scanf("%f", &d);     // You had d, should be &d
a = b;
printf("This is a Fahrenheit to Celcius Conversion Table! \n"); // Don't forget your \n here
while (a <= c)
{
if ((a > 98.6) && (a < (a + d)))
{

printf("%.2f degrees F = %.2f degrees C \n",
98.6, (98.6 - 32.0) * 5.0 / 9.0);

}

printf("%.2f degrees F = %.2f degrees C \n",
a, (a - 32.0) * 5.0 / 9.0);
a = (a + d);
}

return 0;
}```
Here is the output:
Code:
```Enter a value for the starting temperature in Fahrenheit:52
Enter a value for the ending temperature in Fahrenheit:88
Enter a value for the temperature increment value in Fahrenheit:1
This is a Fahrenheit to Celcius Conversion Table!
52.00 degrees F = 11.11 degrees C
53.00 degrees F = 11.67 degrees C
54.00 degrees F = 12.22 degrees C
55.00 degrees F = 12.78 degrees C
56.00 degrees F = 13.33 degrees C
57.00 degrees F = 13.89 degrees C
58.00 degrees F = 14.44 degrees C
59.00 degrees F = 15.00 degrees C
60.00 degrees F = 15.56 degrees C
61.00 degrees F = 16.11 degrees C
62.00 degrees F = 16.67 degrees C
63.00 degrees F = 17.22 degrees C
64.00 degrees F = 17.78 degrees C
65.00 degrees F = 18.33 degrees C
66.00 degrees F = 18.89 degrees C
67.00 degrees F = 19.44 degrees C
68.00 degrees F = 20.00 degrees C
69.00 degrees F = 20.56 degrees C
70.00 degrees F = 21.11 degrees C
71.00 degrees F = 21.67 degrees C
72.00 degrees F = 22.22 degrees C
73.00 degrees F = 22.78 degrees C
74.00 degrees F = 23.33 degrees C
75.00 degrees F = 23.89 degrees C
76.00 degrees F = 24.44 degrees C
77.00 degrees F = 25.00 degrees C
78.00 degrees F = 25.56 degrees C
79.00 degrees F = 26.11 degrees C
80.00 degrees F = 26.67 degrees C
81.00 degrees F = 27.22 degrees C
82.00 degrees F = 27.78 degrees C
83.00 degrees F = 28.33 degrees C
84.00 degrees F = 28.89 degrees C
85.00 degrees F = 29.44 degrees C
86.00 degrees F = 30.00 degrees C
87.00 degrees F = 30.56 degrees C
88.00 degrees F = 31.11 degrees C```

3. Thanks a lot. Seemed to overlook the aspersand (sp?)... Works fine now!

4. ampersand. Sort of like asterisk.
