How to convert the VAR1 variable to VAR2 and vice versa without the need for an auxiliary variable
Example: We have variable 1 and value 10 and variable 2 value 20 and we want to put the value of the first variable in the second variable and the value of the second variable in the first variable
Most programmers rely on the following method:
;int var1,var2,helper
;var1 = 10
;var2 = 20
;helper = var1
;var1 = var2
;var2 = helper
The second method I will write does not need the helper variable so we can only work with var1 var2
;int var1,var2
;var1 = 10
;var2 = 20
;var1 = var1+var2
;var2 = var1 - var2
;var1 = var1 - var
Best of luck
