Turbo C Tutorial

To use Turbo C, you will need to install and run Turbo C version 2.01 on a PC. To start Turbo C, enter TC at the DOS or Windows command prompt.

Tutorial Code

Type in the following C program:

#include <conio.h>

main() {

int a=50;

clrscr();

a+=5;

printf("50 plus five equals %d",a);

getch();

}

Testing

To run the program, press CTRL and F9 or select "Run" from the "Run" menu. If it doesn't work, check the code for mistakes. After looking at the results, press any key to return to the Turbo C interface.

Explanation

The first line adds Turbo C code necessary for data input and output, while the second and third lines initialize the program with a variable set at 50. After this, semicolons separate each command.

The fourth line clears the screen, the fifth adds five to the variable "a" and the sixth line displays the result. Finally, the 7th line instructs the Turbo C program to wait until the user presses a key.
