Program InputOutput; uses crt; var x,y,sum : integer; begin Clrscr; {Entering values into variables x and y} write(‘Input First Number : ‘); Readln(x); write(‘Input Second Number : ‘); Readln(y); writeln; {Perform arithmetic operations with respect to x and y} writeln(‘x + y = ‘, x + y); writeln(‘x - y = ‘, x - y); writeln(‘x * y = ‘, x * y); writeln(‘x / y = ‘, x / y) : 0 : 3); writeln(‘x div y = ‘, x div y); writeln(‘x mod y = ‘, x mod y); Readln ; End.

If the above program code at compile and run the results will be displayed like this :

Output Program :

Input First Number : 10 Input Second Number : 3 x + y = 13 x + y = 7 x + y = 30 x + y = 3.333 x + y = 3 x + y = 1

Program InputOutput; uses crt; var name : string[25]; begin Clrscr; write(‘Input Your Name : ‘); Readln(name); writeln(‘Youre Name Is ’,name); Readln ; End.

Explanation Program:

Line 1    : Indicates that this program has the title First

Line 2    : Indicates that this program uses crt unit

Line 3    :  Declaring variables with the type name string length is 25 characters maximum

Line 4    : Starting the main program block

Line 5    : Clean the monitor screen of the texts that have previously

Line 6    : Shows the information to ask the user to enter their name and position of the cursor is behind the text

Line 7    :  Reading data entered by the user and store it into variable names

Line 8    :  Displays the value contained in the variable name and the position of the cursor will be on the next line

Line 7    : Waiting for the user presses the button

Line 8    : End the program

If the above program code at compile and run the results will be displayed like this :

Output Program :
