This document provides an overview of programming in C including variables, functions like printf and scanf, the switch statement syntax, and demonstrations of C programs. It defines C as a programming language developed in 1973, and describes variables as named memory locations that can store data. It explains the printf function displays values on screen and scanf stores values at memory locations. The switch statement allows different code blocks to execute based on the case, and there are examples of simple C programs that get user input and perform math operations.

- 2. OVERVIEWS About programming in c Variable Function of printf Function of scanf Switch statement syntax Switch flowchart Demonstration in c Some program
- 3. C PROGRAMING:- It is a programung language developed at AT and T Bell labs USA, in 1973 by “Denish Ritchie” Programming language : - It is a problem solving scheme, there are several programing Language today same are c, c++,java, phython, …………etc
- 4. :- It is a named location of memory. It has capacity to store data and its Value can be change during program execution. Variable declaration Syntax <data type> <variable name> As, int num; How to initialize a variable <darta type> <variable name>= value; Example:- int n1,n2,res, choice;
- 5. Function printf() : - We have used it display on the Screen the value contain. The general form of printf() function is:- Printf (“<format string>”, <list of variable>) Example:- printf(“ Enter two Value”);
- 6. scanf function is a must & is an address of operator. It gives the location number used by the variable in memory. When we used “%d”, we are telling scanf(“%d”) at Which memory location should it store the value. Example:- scanf(“%d %d”, &n1,&n2);
- 7. Switch( ) { Case 1; Stetement 1 ; Break ; } As so on…………. default } { Stetement 1 ;
- 8. Case 1; switch defualt Case 2; Case 2; Stop NO NO NO YES YES YES YES res = n1+n2; res = n1/n2; res = n1-n2; “invalid choice”
- 9. #include<stdio.h> or #include.”stdio.h” #include<conio.h> or #include.”conio.h” If we use #include <stdio.h> in c program it will stdio.h file into our source program releted function It is used to include the console input output library function, the getch () function is defined in conio.h file. Void main ( ) The main ( ) function is the entry point of every program in c language.
- 10. Enter two values 1 = add 2 = sub 3 = multi.. 4 = divi…. what you want……..? #include<stdio.h> #include<conio.h> void main () { int n1,n2,res,choice; printf(“enter two values”): scanf(“%d %d , &n1,&n2”); printf(“1 – add/n”); printf(“2 – add/n”); printf(“3 – add/n”); printf(“4 – add/n”);
