Let's go through this example line by line. Let's go through this example line by line.
The first line is the function declaration, we are telling the C compiler that the following block of code is our function called *doSomeMath*, and that it accepts two **arguments** of *int* type: a and b. We are also telling the compiler that the **return type** of the *doSomeMath* function is *int*. The first line is the function declaration, we are telling the C compiler that the following block of code is our function called *doSomeMath*, and that it accepts two **arguments** of *int* type: a and b. We are also telling the compiler that the **return type** of the *doSomeMath* function is *int*.
In the second line (`int result = 0;`) we are declaring one **local variable** of type *int* called *result*. The local variables are stored in memory, so the compiler needs to know how much space to reserve for each variable. In the second line (`int result;`) we are declaring one **local variable** of type *int* called *result*. The local variables are stored in memory, so the compiler needs to know how much space to reserve for each variable.
The following 4 lines are simple statements that can each be translated into single instructions. The following 4 lines are simple statements that can each be translated into single instructions.
The last statement (`return result`) indicates that we want to **return** to the callee (The code that *called* this function) the value inside the *result* local variable.
