TRANSCRIPT
C is developed by Dennis Ritchie
C is a structured programming language
C supports functions that enables easy maintainability of code, by breaking large file into smaller modules
Comments in C provides easy readability
C is a powerful language

Basic Commands C++
Single line comment

Termination of comment is by pressing enter key
Multi line comment
/*….
…….*/
This can span over to multiple lines
Comments in C++
1./* Hello, world program */
2.#include <stdio.h>
3.
4.int main()
5.{
6. printf("hello, ");
7. printf("world\n");
8. return 0;
9.}
Simple Program
Type a program
Save it
Compile the program – This will generate an exe file (executable)
Run the program (Actually the exe created out of compilation will run and not the .c file)
In different compiler we have different option for compiling and running. We give only the concepts.
Running a C Program
Write a program to display your identity with a form below :------------------------------------------------------
