Program to generate Summary of a survey

Posted By: Adalrico Fischer     Category: C Programming     Views: 3366

Suppose that a population survey has been carried in the given city, and that the information received from the survey has been transcribed in to punch cards.Since the cards have 80 cols each, one card contains the name, address,sex, age, profession etc., of one employee. That is , each card contains one record pertaining to one employee. Our problem is to print the details of all the adults in the given city under survey. Finally we also want to print total number of adults. Assume suitable sentinel value for any field in the trailer record and Write a program using structures/file to perform the job.

Code for Program to generate Summary of a survey in C Programming
