{
int? a[20];
int? Length = 20;
int? I,j;
Printf ("Please enter 20 digits");
for(I = 0; I & lt20; i++)
{
scanf("%d ",& ampa[I]);
}
for(I = 0; I< length-1; i++)
{?
for(j = I+ 1; J< length; j++)
{
if(a[i]==a[j])
{
int? k;
Length = length-1;
for(k = j; K< length; k++)
a[k]= a[k+ 1];
}
}
}
for(I = 0; I < length; i++)
printf("%d\n ",a[I]);
} The procedure is correct and the answer is not easy. I hope it can be adopted.
