Input First line N (1<=N<=100). Then NxN table is given(all number are integers) Output The total sum of element that are locate

Question

What is wrong?

#include <iostream>
using namespace std ;

int main (){
int n ,sum ;
cin >> n ;
int aza[100][100];
for (int i=0;i<n;i++){
for(int j=0;j<n;j++){
cin >> aza[i][j];

}
}
for(int i = 0; i < n; i++){
for(int j = 1; j > i; j++ ){
sum += aza[i][j];

}

}

cout << sum;

}

Answer 1

for(int i = 0; i < n; i++){
for(int j = 0; j < n; j++ ){
sum += aza[i][j];
}
}
