For c programing please help

Step #9 - Create a function histogram311 that receives a reference to an array of integer values calculated in the previous step and prints out a histogram showing the counts of the different values. The Y-axis should display count values from 0-19. The function should check the number of elements and return with a -1 value if it is not 10. Otherwise, the function should create a histogram indicating the numbers calculated in Step #8 above. All labels, lines, and framing of the histogram should look like the following (this is exactly what the output for the test input should be, see below). + - - 19 XX XX 18 | xx XX 17 | xx XX 16 | XX XX 15 1..
