Initializing variables in C

Question

I know that sometimes if you don\'t initialize an int, you will get a random number if you print the integer.

But initializing everything to zero seems

Answer 1

I can think of a couple of reason off the top of my head:

1. When you're going to be initializing it later on in your code.

   int x;
   
   if(condition)
   {
       func();
       x = 2;
   }
   else
   {
      x = 3;
   }
   anotherFunc(x); // x will have been set a value no matter what
   

2. When you need some memory to store a value set by a function or another piece of code:

   int x;  // Would be pointless to give x a value here
   scanf("%d", &x);
