C language 1-D arrays
Write a declaration statement for an array with 10 elements. Assume that the array is going to contain double-precision floating-point temperature data in units of Kelvins. Initialize the array with values of 0 in all elements. Write the same declaration, but for an array with n elements, where n is a pre-declared integer variable (In other words, has already been declared in advance.) Do not give the array initial values in this case. (You cannot initialize variable-length arrays in a declaration statement) Write a for loop that will run a total of n times, and in each iteration will set one of the elements of your temperature array to zero. (Remember that arrays in c go from subscript (0) to (n-1). Write a for loop that will run a total of n times, and in each iteration will ask the user for an input value and will store it in a different element of your temperature array. It should also feature a statement that adds the new element to a running sum which is stored in a separate variable called T_sum. Write a statement that calculates the percent error between a variable containing an average measured temperature and a defined symbolic constant containing the boiling point of an unspecified substance. Percent Error = |A-B/B|* 100% (B is the known constant)Solution
