Unit 4 guided practice 1: introduction to arrays | programming | ECPI University

An one dimensional array is a list.  A list of variables.  All those variables have the same name, but they’re differentiated by their subscript, or index.  In the problem below, for example, there is an array called “scores.”  It contains six elements.  Each element has a subscript.  The values are as follows:

scores[0] = 100.00

scores[1] = 100.00

scores[2] =  76.00

scores[3] =  97.00

scores[4] =  72.00

scores[5] = 86.7

Notice the subscripts are “zero based,” that is, the first one is subscript zero, and so on.

If we use these in a program to store grades, we can also use a character array to store the string “ECPI University.”  This program uses a “for” loop to loop through the array elements, and calculate the average grade.

Here is the code:

And here is the output:

Now, you enter the code, and run it.  (No Flowchart this time).

Upload your .c file and a screen shot of your code output saved in a Word document including the path name directory at the top of the screen into the dropbox for grading.
