The walkthrough

This walkthrough is of one of the crackmes to understand how to work on ida

The program takes user input. It generates a number based on an internel algo, the result is always 3. It then compares the user number and generated number.

Two numbers are hard coded, firstnumber = 0x64 and secondNumber = 0xe The algo is as follows: (((firstNumber + firstNumber) + firstNumber) + secondNumber) / firstNumber

============================ [user@comp PieIsMyFav]# ./simple Welcome to the wonderful world of assembly! Qual o numero magico? 3 Essa eh a sua flag! ==========================================

#include<stdio.h>
int main() { 
int firstNumber = 100; 
int secondNumber = 14; 
int userNumber = 0; 
int generatedNumber = 0;
puts("Welcome to the wonderful world of assembly!");
printf("Qual o numero magico? ");

scanf("%d", &userNumber);

generatedNumber = (((firstNumber + firstNumber) + firstNumber) + secondNumber) / firstNumber;

if (userNumber == generatedNumber) {
    puts("Essa eh a sua flag!");
} else {
    puts("Try harder...");
}
