C printf() function:

        printf() function is used to print the “character, string, float, integer, octal and hexadecimal values” onto the output screen.
        We use printf() function with %d format specifier to display the value of an integer variable.
        Similarly %c is used to display character, %f for float variable, %s for string variable, %lf for double and %x for hexadecimal variable.
        To generate a newline,we use “\n” in C printf() statement.

Note:

        C language is case sensitive. For example, printf() and scanf() are different from Printf() and Scanf(). All characters in printf() and scanf() functions must be in lower case.

 

#include <stdio.h>

int main()
{
   char  ch = 'A';
   char  str[20] = "loadyoursystem.blogspot.com";
   float flt = 10.234;
   int no = 150;

   double dbl = 20.123456;
   printf("Character is %c \n", ch);
   printf("String is %s \n" , str);
   printf("Float value is %f \n", flt);
   printf("Integer value is %d\n" , no);

   printf("Double value is %lf \n", dbl);
   printf("Octal value is %o \n", no);
   printf("Hexadecimal value is %x \n", no);

   return 0;

}

C Program to find area and circumference of circle

#include<stdio.h>

int main()
{
int rad;
float PI=3.14,area,ci;

printf("nEnter radius of circle: ");
scanf("%d",&rad);

area = PI * rad * rad;
printf("nArea of circle : %f ",area);

ci = 2 * PI * rad;
printf("nCircumference : %f ",ci);

return(0);
}

Output :

Enter radius of a circle : 1
Area of circle : 3.14
Circumference  : 6.28

Explanation of Program :

In this program we have to calculate the area and circumference of the circle. We have following 2 formulas for finding circumference and area of circle.

Area of Circle = PI * R * R

and

Circumference of Circle = 2 * PI * R

In the above program we have declared the floating point variable PI whose value is defaulted to 3.14.We are accepting the radius from user.

printf("nEnter radius of circle: ");
scanf("%d",&rad);
