Didn’t get why is it 34 in output, when I write X =3, n = 1...it has to be X...what am I doing with my life...

Question

#include <iostream>

//у = х^(1^2)+ х^(2^2)+...+_•
using namespace std;

int main() {
int n,p;
int x;
int result = 0;
cin>>x;
cin>>n;
x = p;
if(n!=1){
for(int i = 2; i<=n;i++){
for(int k =1; k <=i*i; k++){
x=x*x;
}
result = result +x;
}
//x - its x^1
cout<<result+x;
}else

cout<<x;

}

Answer 1

Ah, alright. Well, the problem is that you modify x directly in your loop, so it increases and increases while it should remain its initial value. You need to use some temporary variables here. Here is a solution without <cmath>:

wow.... thanks!!!

Answer 3

You could ease your life quite a bit if you used existing libraries. <cmath> provides a lot of maths functionality you can use instead of writing all those loops by yourself. This is how a simplified version could look:

Here you can find an overview of its entire functionality:

On a sidenote, the problem is most likely related to the statement
x = p;
Here, p is still not initialized, since you never provided a value for it, so it has some garbage value which was stored in that particular memory cell before, and you set x to that garbage value too, resulting in x nlt being the number the user entered before. Maybe you meant to write
p = x;
instead, so that p equals the value of x?

i woud like to use math.h, but my task is to write code without it
