compound_interest.c

// This is the program to calculate the compound interest rate .

/* Sample Input :
    Enter the principle amount : 1000
    Enter the interest rate: 12.5
    Enter the time period : 2
    Enter number of times interest is compounded yearly : 2
   Sample Output :
    The simple_interest is : 2761816.500000
