Standard Input/output Functions in C

 Standard input/output functions


  1. character based functions

            1.getchar()

            2.getche()

            3.getch()

            4.gets(char*)

            5.putchar(char)

            6.puts(char*)

      

  2. format based function


      scanf() - for accept

      printf() - for display



      1. format specifier

      2. address of variable


      In case printf there is no fixed number of argument

      printf("hello")


      int n1=5,n2=10

      Sum of 5 and 10 is 15

      printf("Sum of %d and %d is %d",n1,n2,n1+n2)


     to disy n values the number of argument is n+1

Functions

  What is Function ?    In a Program to perform articular task number of times which is having more number of statements, instead of writing those statements number of time we can define a sub routine called Function. The purpose of function is reusability. Function has three parts 1. Function declaration - before the main() 2. Function Calling - within the main() 3. Function Definition - after the main() Functions are following categories 1. Functions with no arguments, no return value 2, Functions with arguments, no return value 3. Function with arguments and return value while giving the function definition we can use as follows    type specifier function_name(arg1,arg2,...)    {       statements;    } In the above type specifier represent what type of value the function is going to return. If the function can't return any value we can represent with void otherwise we can use any related data type. to return the va...

  //Find out sum of two numbers is even or odd main() { int n1,n2,sum; printf("value for n1"); scanf("%d",&n1); printf("value for n2"); scanf("%d",&n2); sum=n1+n2; if(sum%2==0) printf("\n%d is even",sum); else printf("\n %d is odd",sum); } //Accept a character and check whether it is vowel or not main() { char c1; printf("Enter a character"); scanf("%c",&c1); switch(c1) { case 'a': case 'A': case 'e': case 'E': case 'i': case 'I': case 'o': case 'O': case 'u': case 'U': printf("\n%c is vowel",c1);           break; default:printf("\n%c is not vowel",c1);           break; } } // display the numbers between 1 and 10 main() { int n; for(n=1;n<=10;n++) printf("%d ",n); } // display the numbers between 1 and 10 usi...

SQL Operators

Operator The purpose operators is to perform the manipulations with attributes. These Operators are following 1. Relational Operators - for comparing purpose 2. Arithmetic Operators - for mathematical operations 3. Logical Operators - for compare with multiple conditions or opposition conditions 3. Special Operator - for special purpose comparison Relational Operators >, <, >=, <=, =, !=, <> Examples: Display the details about employee whose name is SMITH select *from emp where ename='SMITH'; Display the details about employees whose salary is greater than 3000 select *from emp where sal > 3000; Display the details about employees except MANAGER select *from emp where job <>'MANAGER' ; or select *from emp where job !='MANAGER' ; Arithmetic Operators +, -, *, / Logical Operators and, or , not Example Display the details about MANAGERS whose salary is greater than 2500 select ename, job, sal from emp where job='MANAGER' and sal...
