reseting a variable

[cb32]

How can I reset the number assigned to a variable after it reaches the end of the code within a function?

Please give us some example code to show us what you mean. Currently, I think you mean this:

void function()
{
  int x = 6;
  // LOTS OF CODE
   
  // HOW DO I SET THE VALUE OF X HERE?
}

example

#include <iomanip>
using namespace std;

int main (){
int y = 1;
int n = 0;

cout<<"would you like to perform a computation? ";
cin>>answer;

if (answer = 1){
function()
   }
else if (answer = 0){
exit(0);
   }
}
function(){
int variable;
cout<<"input variable for random calculations: ";
cin>>variable;
cout<<variable<<"squared is: "<<variable * variable;

//I would like to have some way to reset variable right here so that when it's called
//again in the redo function it doesnt loop the final cout statement of the function()

redo()
}
redo(){
cout<<"would you like to do this again? ";
cin>>yesNo;
if (yesNo = 1){
function();                        //
}
else(){
exit(0);
}
}

[Moschops]

In this code, every time function is called, a whole new int variable is created. A whole new one. Any int variable from a previous call to function has no effect whatsoever.

I found my issue then! Thanks Moschops. I had my variable set as a global rather than inside my function so it was never reverting back to the originally undefined variable.

Another problem with your code, is you are using assign instead of checking the variable values.

ex.
if (answer = 1)
should be
if (answer == 1)

same with the
else if (answer = 0)
should be
else if (answer == 0)

and also
if (yesNo = 1)
should be
if (yesNo == 1)
