citire+afisare vector
#include<stdio.h>
#include<conio.h>
int v[30][30],i,n;
void main()
{ clrscr();
printf("\n dimensiunea este:");
scanf("%i",&n);
for (i=0;i<n;i++)
{printf("\n v[%i]=",i);
scanf("%i",&v[i]);
}
for (i=0;i<n;i++)
printf("%i",&v[i]);
...
getch();
}

citire+afisare matrice
#include<stdio.h>

}
for (i=0;i<n;i++)
{for (j=0;j<n;j++)
printf("%5i",&a[i][j]);
printf("\n");
