How to remove repeated elements from Arrays

// Original] how to remove repeated elements from Arrays

# Include <stdio. h>

Int main ()

{

Int a [5];

Printf ("input five numbers :");

For (int I = 0; I <5; I ++)

{

Scanf ("% d", & a [I]);

}

Int len = 5; // 5 5 5 2 5

// Two for loops are used to traverse

For (int j = 0; j <len; ++ j)

{

For (int m = j + 1; m <len; ++ m)

{

If (a [j] = a [m])

{

// Use the overwrite method to delete the same element as the first for statement.

For (int k = m + 1; k <len; ++ k) // there will be differences in writing-According to k = m + 1, may be a len-1 or other...

A [k-1] = a [k];

Len --; // keep up with the length

-- M; // because an element is deleted, the subscript of the array element to be compared with a [j] does not change but the value has changed)

}

}

}

For (int n = 0; n <len; ++ n)

{

Printf ("% d", a [n]);

}

Printf ("\ n ");

Return 0;

}
