From a reverse engineering perspective, it is important to identify the branching/conditional statements. To do that, it is essential to understand how branching/conditional statements (like if, if-else and if-else if-else) are translated into assembly language. Let's look at an example of a simple C program and try to understand how the if statement is implemented at the assembly level:
if (x == 0) { x = 5;}x = 2;
In the preceding C program, if the condition is true (if x==0), the code inside the if block is executed; otherwise, it will skip the if block and control is transferred to x=2. Think of a control transfer as a jump. Now, ask yourself: When will the jump be taken? The jump will be taken when x is not equal to ...
