Compile Time Initializing 1-D Array [ Different Methods ] in C Programming

Different Methods of Compile Time Initializing 1-D Array

1. Size is Specified Directly
2. Size is Specified Indirectly

Method 1 : Size Specified Directly

• Here Size of an Array is Specified Directly.
• Example :

int num[5] = {2,8,7,6,0};

• Size of An Array : 5
• As at Compile Time All Elements are at Specified Position So This Initialization Scheme is Called as “Compile Time Initialization“

Method 2 : Size Specified Indirectly

• Here Size of an Array is Specified Indirectly.
• Example :

int num[] = {2,8,7,6,0};

• Indirectly Compiler Counts the Number Of Elements Written Inside Pair of Braces and Determines the Size of An Array .
• Here Array Size is 5
• This Initialization Scheme is also Called as “Compile Time Initialization“
