Write a C program to do currency conversion. The program will display a title "Currency Conversion," ask the user to enter the amount in US dollars, and then convert it into 5 foreign currencies. The program will then output the names of five currencies and their equivalents to US dollars. Use the exchange rates below.

1 Swiss Franc = 0.6072 US dollars
1 British Pound = 1.4320 US Dollars
1 Japanese Yen = 0.0081 US DOLLARS
1 Canadian Dollar = 0.6556 US Dollars
1 Euro                 = 0.8923 US Dollars

Think what you have to do:

First,you need to get the dollar value from the user.Take a float.
float dollar;

Then,conversion requires multiplication with the values you have provided above.These are decimal values as well,so use float for them as well.
//similarly for the other currencies as well.

Multiply the dollar with the conversion value and you have the converted value.

Use printf() to display the text and the converted value.

Lets say you define euro as:
float euro=0.8923;

>The program will then output the names of five currencies and their equivalents to US >dollars.

1 USD=1/euro

Use printf() to print these values out for all the five currencies.

Now are you doing the homework for him/her after all. Writing the code would have been a lot faster, about 12 lines would be enough, wouldn't it?

ShnHutson: do you have a good book on C? I have a very old Kernighan & Ritchie "The C Programming Language", and you can find a similar program on page 8 already! (Celsius-Fahrenheit conversion)

Thanks for the help, I don't have any books on C. Only the teacher's weekly notes. What you have posted helped me out the rut.

I accepted it because I pieced together some of the comments that were made. I was running out of time.
