5. Se consider˘a programul:
Varianta Pascal Varianta C/C++

#include <iostream.h>
var i,j:integer;
using namespace std;
a:array [1..6 ,1..6] of integer;
int main (){
begin
int i,j,a[7][7];
for i:=1 to 6 do
for(i=1;i<7;i++)
for j:=1 to 6 do
for(j=1;j<7;j++)
a[i,j]:=0;
a[i][j]=0;
for i:=2 to 6 do
for(i=2;i<7;i++)
for j:=2 to 6 do
for(j=2;j<7;j++)
a[i,j]:=i*j mod 6;
a[i][j]=i*j%6;
for i:=1 to 3 do
for(i=1;i<4;i++){
begin
for(j=1;j<4;j++)
for j:=1 to 3 do
cout <<a[i][j];
write(a[i,j]);
cout <<endl;
writeln;
}
end;
return 0;
end.
}
Dup˘a executare, se va afi¸sa:

6. Se consider˘a:

Varianta Pascal Varianta C/C++
function ex(k:longint ): integer; int ex(long k){
begin if (k==0)
if k=0 then return 1;
ex:=1 else
else if(k%10!=0)
if k mod 10<>0 then return ex(k/10)*(k%10);
ex:=ex(k div 10)*(k mod 10) else
else return ex(k/10);
ex:=ex(k div 10); }
end;
