How Start the C program-Day1

How to write a C-program:

I'm using DevC++:


1.Open IDE(Integrated Development Environment):
2.File--->New----->Source File(Shortcut    ctrl+N)
3.Type the Below Program
4.File--->save(choose the location where you want to save your c-programs)
   give any filename.c
   eg: Hello.c

5.compile the code  Click on Execute---->compile(Shortcut F9)
6.Run the program  click on execute----->Run(Shortcut F10)

program-1:

#include<stdio.h>
int main()
{
       printf("Hello guys!... This is my new program");
       return 0;
}










Escape Sequences:


Escape sequence: These are special symbols used to escape the sequential order of execution.

These are shown with a backslash(\) followed by the respective character.

\n    take the cursor to next line
\b    backspace
\t     tab space (8 character spaces)
\"     double inverted comma(")         
\\     shows a backslash on the console
\'      single inverted comma(')
\a     alert message(works only with speakers)

\n--------->new line
\t---------->tab space
\a---------->alert(which give some alert sound when  you run the program)
\b--------->Back space

output without escape sequences


#include<stdio.h>
int main()
{
       printf("Hello");
       printf("krishna");
       printf("thank you");
       return 0;
}


output:   Hellokrishnathank you



output with escape sequences


#include<stdio.h>
int main()
{
       printf("Hello\n");
       printf("krishna\t");
       printf("thank you");
       return 0;
}



output:  Hello
             Krishna        thank you
