se da o matrice de numere intregi sa se afiseze elementele comune tuturor linilor matricei

Answer 1

#include <iostream>

#include <cstring>

using namespace std;

int main() {

int mat[100][100];

int n, m;

cin >> n >> m;

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

for (int j = 0; j < m; j++)

cin >> mat[i][j];

for (int j = 0; j < m; j++) {

int gasit_toate_liniile = 1;

for (int lin = 1; lin < n; lin++) {

int gasit_linie = 0;

for (int col = 0; col < m; col++) {

if (mat[lin][col] == mat[0][j]) {

gasit_linie = 1;

break;

}

}

if (gasit_linie == 0) {

gasit_toate_liniile = 0;

break;

}

}

if (gasit_toate_liniile)

cout << mat[0][j] << " ";

}

cout << "\n";

return 0;

}
