The lenght and breadth of a rectangle and radius of a circle are input through the keyboard . write a program to calculate the area and perimeter of the rectangle and the area and circumference of the circle.

By Rohit -
// program to calculate area of rectangle and circle.
# include<stdio.h>

int main(){
    int l,b,r;
    float rectangle ,circle,area,perimeter,circumference;
    printf("Enter the lenght , breadth:\n ");
    scanf("%d%d",&l,&b);
    rectangle=l*b;
    perimeter=2*(l+b);
    printf("The Area of reactangle is %f and\n
perimeter of rectangle is %f\n",rectangle,perimeter);

    printf("Enter the Radius of the circle:\n");
    scanf("%d",&r);
    circle=3.14*r*r;
    circumference=2*3.14*r;
    printf("The Area of circle is %f
and \nthe circumference of circle is %f",
circle,circumference);


    return 0;
}
/*output*/
Enter the lenght , breadth: 2 3 The Area of reactangle is 6.000000 and perimeter of rectangle is 10.000000 Enter the Radius of the circle: 5 The Area of circle is 78.500000 and the circumference of circle is 31.400000

Table of Content Introduction of loop Types of loop while loop do while loop for loop nesting of loop infinite loop odd loop difference between while loop and do while loop Introduction of loop  Loop are used when we want to execute a block of statement or a part of program at multiple times. suppose a program to print " hello world " 20 times. one way to get the desired output using printf statements, which is bad programming skill or not preferable . other way we can use loop to print the "hello world " easily.   Now I can demonstrate to you print " hello world " without using loop. /*Program to print "hello world" without using loop*/ #include <stdio.h> int main() {     printf( "hello world\n" );     printf( "hello world\n" );     printf( "hello world\n" );     printf( "hello world\n" );     printf( "hel...

Type conversion and Type Casting

 Type conversion Type conversion  in C is the process of converting one data type to another.  The type Conversion is only performed to those data types where conversion is possible. Type conversion is performed by a compiler. In type Conversion data type can be convert lower rank into higher rank. Implicit Type Conversion These conversion are done by the compiler according to some predefine rules of C language. The two types of implicit conversions are automatic type conversion and type conversion in assignment. Generally take place when in an expression more than one data type is present. In such condition type conversion(type promotion) takes place to avoid loss of data. All the data types of the variable are promoted to the data type of the variable with the largest data type. char-> short int-> int-> long int-> float-> double-> long->double Implicit type conversion is also called automatic type conversion. some of its few occurrences are mention ...

Digraph and Trigraph characters in C

By Rohit -
Digraph Character : The Diagraph are sequence of two character that the compiler replaces with their corresponding punctuation character. Digraph sequence Symbol <% { left brace %> } right brace <: [ left bracket :> ] right bracket %: # hash %: include <stdio.h> int main() <%     printf( "Hello world!" );     return 0 ; %> which is treated the same as :- #include <stdio.h> int main() {       printf( "Hello world!" );     return 0 ; } Trigraph Character : Trigraph are sequence of three characters (introduced by two consecutive Question marks ) that the compiler replaces with their corresponding punctuation characters.  some keywords may not have all the characters from the C character set. C supports the facility of "trigraph sequence" to print these characters. These trigraph sequences have three characters. First two are '??' and third character from C character set. some trigraph sequences are as given...
