C language, how to calculate the maximum value and secondary limit after removing repeated elements in the array

// Original] C language, how does an array calculate the maximum value and secondary limit after removing repeated elements?

# Include <stdio. h>

Int main ()

{

Int a [7];

Printf ("input seven numbers :");

For (int I = 0; I <7; I ++)

{

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

}

Int len = 7; // 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 (I = 0; I <len; I ++)

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

Printf ("\ n ");

Int temp;

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

For (int p = n + 1; p <len; p ++)

If (a [n] <= a [p])

{

Temp = a [n];

A [n] = a [p];

A [p] = temp;

}

For (I = 0; I <len; I ++)

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

Printf ("MAX = % d, S_MAX = % d \ n", a [0], a [1]);

Return 0;

}

// Running result

// Input seven numbers: 7 5 7 5 8 6 8

// 7 5 8 6

// 8 7 6 5 MAX = 8, S_MAX = 7

// Press any key to continue
