Problem 77. C Program to print a frequency distribution table for a class of 20-students in the following format. The marks range form 1-25.
class intertval                frequency
     1.5                               1-5
     6.10                             6-10
     11.15                         11-15
     16.20                         16-20
     21.25                         21-25
