This document contains a C programming language project submitted by a student. It includes an introduction to C programming, advantages and disadvantages, examples of simple programs to calculate sums, interests, and temperature conversions. It also provides the source code and output for these example programs. The project covers basic concepts like variables, input/output, decision statements, loops, and functions through these illustrative examples.

C PROGRAMMING
INTRODUCTONOF C PROGRAMMING
C Programming is a structure oriented programming language which was developed
dennnis Ritchie in 1972 at bell liboratory in USA this language is high level language
like English language for the development of different software and application
software c programming language is also develop c++ programming language using
platform it support compiler or interpreter for hardware interfacing or different
electronic device like as for developing robotics and export syste
ADVANTAGES OF C PROGRAMMMING1
The advantagesof c prorammmingare as follows:
1)It is easier interactwith hardware
2)It is easy to run
3)program codeis secured
4)It is compactcan easier
DISADVANTAGES OF C PROGRAMMING
The disadvantagesof c programmingare as follows:
1)It does not contain run time error
2)There is no strict type of checking
3)it is difficult to fix bug.

I want to conclude that, using above all codes many program can be made
which makes user to write program in simple and easy way. C programming
language has made new technologies evolve.
