How to make this simple?

How to make my code simple? i wrote it for little practice but end up being a long enough code.

Just glancing at your code I would say it could benefit from

Functions:
Switches:
Structures/Classes:

I would say start with refactoring this

   string Name;
    int Gender;
    int Birthdate;
    int BirthMonth;
    int BirthYear;
    int age;
    int fileEx;

into a class/struct

Why would you want to shorten it?
If it works then your in the clear. Also PC's now in days can run some HEAVY programs and you don't necessarily have to worry about memory space because now in days PC's have quite a bit.

[GibsRey]

Okay then, i don't really wanted to shorten it, I just thinking Maybe there are some suggestions

ehh ok...

@GibsRey. Look into what @BDanielz wrote to you. Learn about classes, functions and switches.
It'll be much better if you shorten it, or divide it into files(classes).

The addition/multiplication/division/subtraction function could be made very simpler. It doesn't even need a function actually. Check this.

#include<iostream>
using namespace std;

int main(){

int n;
cout<<"Enter the amount of numbers:\n";
cin>>n;
int nums[n];
cout<<"Enter the numbers:\n";
for (int i=0; i<n; i++){
    cin>>nums[i];
}
cout<<"Now enter the operators (without using spaces)";
string op;
cin>>op;
int final_ans = nums[0];
for (int i=1; i<n; i++){  // < i = 1 because we've initialized the final_ans with the value of nums[0]
    if (op[i-1]=='+'){
        final_ans = final_ans + nums[i];
    }
    else if (op[i-1]=='-'){                 // i-1 so we can start from the start
        final_ans = final_ans - nums[i];
    }
    else if (op[i-1]=='*'){
        final_ans = final_ans * nums[i];
    }
     else if (op[i-1]=='/'){
        final_ans = final_ans / nums[i];
    }
}
cout << final_ans;
}

Classes Huh? @TarikNeaj
That's a good idea, i will try it!
making header Files and include them makes program looks a bit short.
ehh ok...
