Some command used in c programming

Text formatting

1.       Text color()

2.       Text background()

3.       Cprintf()

4.       Gotoxy()

1.    textcolor()

Textcolor() is the function, used to set color into the output text.

Syntax:

Textcolor(<color_constant>);

[note: constants are always written in upper case(capital letter)]

Example

          Textcolor(GREEN);

          Cprintf(“trees!”);//this will be printed in green color.

Note: cprintf and printf are exactly same. Cprintf() can display/output the test in the color set by textcolor();

Text Effect (blink) can also be set using textcolor().

          Textcolor(RED+BLINCK);

          CPRINTF(“Attention!!”);

[onlu visible during full screen execution]

2.    textbackground():

is the function used to set the background color of the output text.

Syntax:

textbackground(<color_constant>);

          eg

textcolor(RED);

textbackground(YELLOW);

cprintf(“press any key to continue”);

textbackground(BLUE):

clrscr();

3.    gotoxy()

gotoxy() is used to place the cursor in a specific place of the console.

          Void main()

          {

                   Textcolor(RED);

                   Cprintf(“student mgmt system!”);

                   Cprint(“\n Sibmitted byJ:

          }

Syntax

gotoxy(x-coordinate,y-cordinate);

eg

gotoxy(10,10);

cprintf(“hellow”);

gotoxy(10,11);

cprintf(“__”);
