Create a form with two text boxes (txtNumber1, and txtNumber2) and a command button (cmdSwap).
Option Explicit
Dim numb1 As Variant
Dim numb2 As Variant
Private Sub cmdSwap_Click()
numb1 = txtNumber1.Text
numb2 = txtNumber2.Text
txtNumber2.Text = numb1
txtNumber1.Text = numb2
End Sub
MS-DOS QBasic Version 1.1
SWAP Exchanges the values of two variables.
SWAP variable1, variable2
variable1 and variable2 Two variables of the same data type.
Example:
a% = 1: b% = 2
PRINT "Before: "; a%, b%
SWAP a%, b%
PRINT "After: "; a%, b%
swap two value by visual basic
void swap (int *a, int *b) { *a ^= *b; *b ^= *a; *a ^= *b; return; }
By using the algorithm of bitwise EORing (Exclusive ORing) the numbers together:If the two numbers are X and Y, then to swap them:X = X EOR YY = Y EOR XX =X EOR Ywill swap them.With knowledge of that algorithm, one then uses the syntax of Javascript to implement it.
You need a code that can run to print even numbers between 10 and 100 using the qbasic command.
the two types of data used in Qbasic is numeric data and alpha numeric data.
Cls input"no. Of elements",n for i=1 to n input,a(i) next i for i=1 to n-1 for j=i+1 to n if a(i)>a(j) then swap a(i),a(j) next j next i for i=1 to n print, a(i) next i end
Statement numbers were a feature of BASIC, and while QBASIC supports them, they are by no means necessary.
void swap (int *a, int *b) { *a ^= *b; *b ^= *a; *a ^= *b; return; }
You use the relevant formula.
swap (int *a, int *b) { *a ^= *b; *b ^= *a; *a ^= *b; }
void swap(int& a, int& b ) { a^=b^=a^=b; }
Difference between QBASIC and GWBASIC?
You cannot swap two numbers using call by value, because the called function does not have access to the original copy of the numbers.Swap with call by reference... This routine uses exclusive or swap without temporary variable.void swap (int *a, int *b) {*a ^= *b;*b ^= *a;*a ^= *b;return;}
By using the algorithm of bitwise EORing (Exclusive ORing) the numbers together:If the two numbers are X and Y, then to swap them:X = X EOR YY = Y EOR XX =X EOR Ywill swap them.With knowledge of that algorithm, one then uses the syntax of Javascript to implement it.

I don't know.the Switch-A-Roo? not,it's inverse.
