Question

Given the following declaration:

char inputBuffer[12];

What is the default value of either char within the array? I\'m interested in knowing thi

Answer 1

The array elements have indeterminate value except if the array it is defined at file-scope or have static storage-class specifier then the array elements are initialized to 0.

 #include 

 char inputBuffer1[12];          // elements initialized to 0
 static char inputBuffer2[12];   // elements initialized to 0

 void foo(void)
 {
     char inputBuffer3[12];         // elements have indeterminate value!
     static char inputBuffer4[12];  // elements initialized to 0
 }
