media aritmetica a elementelor matricii
Fiind data o matrice a cu m linii si n coloane cu elemente numere intregi,determinati media aritmetica a elementelor matricii
#include<iostream.h>
void main()
{
int n,m,i,j,a[20][20];
int nr,s=0;
cout<<"m=";cin>>m;
cout<<"n=";cin>>n;
for(i=1;i<=m;i++)
for(j=1;j<=n;j++)
{cout<<"a["<<i<<"]["<<j<<"]=";cin>>a[i][j];}
for(i=1;i<=m;i++)
for(j=1;j<=n;j++)
s=s+a[i][j];
cout<<"suma elementelor este:"<<s<<endl;
nr=m*n;
cout<<"nr de elemente este:"<<nr<<endl;
cout<<"media aritmetica:"<<(float)s/nr;
}

media aritmetica o calculezi cu instructiunile din program in variabila ma in functia float m(int a[10][10],int l, int c)
si inainte de a inchide functia faci return ma

#include
#include
using namespace std;
ifstream f( "22.in" );
ofstream g( "23.out" );
int a[10][10],l, c,s;
void citire(int a[10][10],int l, int c)
{
int i,j;
for(i=1;ia[i][j];
}
int main()
{
int s, l, c, i, j;
f>>l>>c;
citire(a, l, c);
for(i=1; i
