POMaking a Menu in QBasic
text
Body
copied!<p>I am making a simple calculator in QBasic, for that want to implement a Menu, the practice which I followed was: </p> <pre><code>PRINT "Select an Option" PRINT "1. Addition" PRINT "2. Subtraction" PRINT "3. Multiplycation" PRINT "4. Division" PRINT "Option No.: " INPUT opt CLS SELECT CASE opt CASE 1 PRINT "You have selected Addition" PRINT "Enter a no.:" INPUT n1 PRINT "Enter second no.:" INPUT n2 PRINT "The Sum is "; n1 + n2 CASE 2 PRINT "You have selected Subtraction" PRINT "Enter a no.:" INPUT n1 PRINT "Enter second no.:" INPUT n2 PRINT "Difference between "; n1; " and "; n2; " is "; n1 - n2 CASE 3 PRINT "You have selected Multiplycation" PRINT "Enter a no." INPUT n1 PRINT "Enter second no.:" INPUT n2 PRINT "Product is "; n1 * n2 CASE 4 PRINT "You have Selected Division" PRINT "Enter a no.:" INPUT n1 PRINT "Enter second no.:" INPUT n2 PRINT "The Quotient is "; n1 / n2; " and the remainder is "; n1 MOD n2 CASE ELSE PRINT "Invalid Option Number" END SELECT </code></pre> <p>But this time I want a more sophisticated one, like:<br> (A)dd Numbers<br> (S)ubtract Numbers<br> (M)ultiply Numbers<br> (D)ivide Numbers<br> This all in a Box that is centered on the Screen. I am using <code>LOCATE</code>, but I am not getting the results I want, and yes I am trying this without Graphics. I'm also using <code>INKEY$</code> to get the key entered by user. I tried <code>INPUT</code> but it echoed the character typed by user. </p> <p>EDIT: @user2864740, it means that I was not able to get the perfect coordinates.</p>
