CGoto

---

(C) goto

keyword enabling you to make jumps in your code.

You can only jump to the same code block you jump from:

void func1(void)
{
  goto labelFunc2; //Error: Undefined label 'labelFunc2'
}
void func2(void)
{
  labelFunc2:
}

Using goto is considered bad programming practice [?], the use of for and  ?while is more appreciated. The active use of goto results in code that is called  ?spaghetti code.

You could use goto when you want to end multiple loops, as the break command only breaks one loop.

include <stdlib.h>


int myFunction()
{
  return rand()%1000;
}
int main()
{
  int x = 0;
  int y = 0;
  int z = 0;
  int maxy = 1000;
  int maxx = 1000;
  int maxz = 1000;
  for (z=0; z<maxz; z++)
  {
    for (y=0; y<maxy; y++)
    {
      for (x=0; x<maxx; x++)
      {
        if (myFunction()==0) goto afterloop;
      }
    }
  }
  afterloop:
  return 0;
}
