do{


printf("Insert datel= \n"),scanf("%d/%d/%d",&a,&b,&c);

if (a>z1 && b>z2 && c>z3)
{
z1=a,z2=b,z3=c;

while (a!=0&&b!=0&&c!=0);

printf("the earliest date up above is = %d/%d/%d \n",z1,z2,z3);

system("Pause");
}

a) Your formula for earliest date is incorrect.
b) In the first iteration of your loop, z1, z2 and z3 have no value (not initialized). Set it to an initial value before the loop begins.
c) Don't use system() commands!
