printf example in C

Header file:

     stdio.h

Synopsis:

     int printf(const char *format, ...);

Description:

     It is equivalent to fprintf.  Performs the formatted output conversion and writes the output to stdout.  It gives us the number of characters printed (excludes '\0') as output.

printf function C example:

  #include<stdio.h>
  int main() {
        int a = 10;
        float b =10.11;
        char ch = 'a', str[100] = "see-programming.blogspot.com";
        printf("Integer a:%d\n",a);
        printf("Float b:%f\n", b);
        printf("Char ch:%c\nString str:%s\n", ch, str);
        printf("Return value of printf: %d\n",
                printf("Hello world\n"));
        return 0;
  }

  Output:

  jp@jp-VirtualBox:~/$ ./a.out
  Integer a:10
  Float b:10.110000
  Char ch:a
  String str:see-programming.blogspot.com
  Hello world
  Return value of printf: 12
