    Need help with a array program

    i need help wit the logic to write the program.

    Design an algorithm that takes an array of five (5) double data type elements, which represent exchange rates (e.g. U.S. Dollar->E.U. Euro), and use a switch statement to display/output that number. Use a random number function in C (this will require the randomize() function too) to pick what case to use.

    Welcome to the forum, antim!

    Use the same logic you would use to do this, by pencil and paper.
    The logic is the same. What specifically, has you stumped?

    Are you stumped about the "do my homework" rules, the "read forum rules before posting" or writing in ENGLISH and not SMS speak ?
    1. Get rid of gets(). Never ever ever use it again. Replace it with fgets() and use that instead.
    2. Get rid of void main and replace it with int main(void) and return 0 at the end of the function.
    3. Get rid of conio.h and other antiquated DOS crap headers.
    4. Don't cast the return value of malloc, even if you always always always make sure that stdlib.h is included.
