c++​

Answer 1

#include <iostream>

using namespace std;

int main(){

int a[100][100],n,i,j,s=0;

//Citire matrice + calculare suma

cin >> n;

for(i=0;i<n;i++){

for(j=0;j<n;j++){

cin >> a[i][j];

s+= a[i][j];

}

}

//Afisare matrice

for(i=0;i<n;i++){

for(j=0;j<n;j++) cout << a[i][j] << " ";

cout << endl;

}

//Afisare suma

cout << s;

}
