Good evening to all,...
i wrote a small algorythm (in C ) to find how many uniqe value are in an
array ..
then change the size of the array to store all the unique values ..
code you please look at the code and make changes to it (to)
/*
This program Should find the true length of an array (the number of
uniqe values)
then create a new array and copy all the unique values onto it.
It is relased with the GNU licence

#include <stdio.h>

int truelength(int *arr,int *temp,int size){
int i=0,j,e=1,n=0;
//temp=(int *) malloc(sizeof(int)*size);
temp[0]=arr[0];
while(i<size){
for(j=0;j<n;j++)
if(arr[i]==temp[j])
{
e=0;
}
if(e==1)
{
temp[n]=arr[i];
n++;
}
i++;
e=1;
}
//This will shrink the corrct amount of mem ..
temp=realloc(temp,sizeof(int)*n);
return n;
}
int main(){
int i,e,n,j,size,*ptr,*temp,*newarry;
printf("Please enter the size ");
scanf("%d",&size);
ptr=(int *) malloc(sizeof(int)*size);
for(i=0;i<size;i++)
scanf("%d",&ptr[i]);
temp=(int *) malloc(sizeof(int)*size);
n=truelength(ptr,temp,size);
printf("The size of the array %d",n);
for(i=0;i<n;i++)
printf("%d ",temp[i]);
free(temp);
free(ptr);
return 0;
}
