It is one of the most popular computer languages today, because it is a structured, high level, machine independent language. The root of all modern language is ALGOL, introduced in early 1960’s. ALGOL was the 1st computer language to use a block structure. Subsequently, several other languages were announced after 1960’s. In 1967, Martin Richard developed a language called BCPL i.e. basic combined programming language mainly for writing system software. In 1970, Ken Thompson created a language using many features of BCPL and called it simply B. B was used to create early version of UNIX operating system. C was evolved from ALGOL, BCPL, and B by Dennis Ritchie at the Bell Laboratories in 1972, strongly associated with UNIX. During 1970’s, C had evolved into the “TRADITIONAL C”. With the publication of the book ‘The C Programming language’ by Brian Kernighan and Dennis Ritchie in 1978, it becomes more powerful. In 1983, American National Standards Institutes (ANSI) appointed a technical committee to define a standard for C. The committee approved a version of C in December 1989, which is now known as ANSI C. It was then approved by International Standard Organization (ISO) in 1990. INTRODUCTION: We have discussed so far various features of C language and are ready to write and execute program of modest complexity. However, before attempting to develop complex programs, it is worthwhile to consider some programming techniques that would help design efficient and error free. The program development process includes three important stages, namely, program design, program coding and program testing. All the three stages contribute to the production of high quality program. In “University Course Details Management System” we have done system design, source coding, and program testing and added many more features to facilitate the user with the best. We have given the user the facility to enter the Student’s record and see whether the user is provided with the complete information. We can improve the efficiency of the system, thus overcome the drawbacks of the existing system. · Less human error · Strength and strain of registers and papers can be reduced · High security · Data consistency · Easy to handle · Easy data updating · Easy record keeping · Backup data can be easily generated Introduction of program management system We can make this Student record management system in C language by using three or more than three header files or many data types such as: 1. #include<stdio.h> : this header file will contain Scanf() , Printf () And, there are many header files which are used in this program…. 2. #include<conio.h>: this header file will contain Clrscr(); , Getch(); , and many more…. 3. #include<string.h> : this header file will contain string function. 4. #include<ctype.h> SYSTEM REQUIREMENTS Operating System: RAM: HARD DISK Processor Compiler Windows 2000/NT/Xp/Vista 256 MB or more 40 GB or more P3 or High Standard C++ Compiler SYSTEM DESCRIPTION THE OPERATING SYSTEM USED IN THIS PROJECT IS WINDOWSXPIT HAS MICROSOFT OFFICE INSTALLED IN IT.

THESE CONVERSIONS HAS TO DONE CAREFULLY. MAINLY THERE ARE TWO TYPES OF TESTING: 1-SYSTEM TESTING AND 2-INTEGRATION TESTING SYSTEM TESTING INVOLVES WHOLE TESTING OF PROGRAM AT ONCE AND INTEGRATION TESTING INVOLVES THE BREAKING OF PROGRAM INTO MODULES & THEN TEST. FUTURE SCOPE In future one change can be done by adding the fingerprints of the student of which the record is entered. And one more major change which can be done in this project is that to add the snaps of the student of which the record is entered. We can also add or subtract details of the individual.
