Problem 6-2 using a special seek function string and the number of columns

 1 #include <stdio.h>
 2 
 3 int fn(int a, int n);
 4 int SumA(int a, int n);
 5 
 6 int main()
 7 {
 8     int a, n;

10     scanf_s("%d %d", &a, &n);
11     printf("fn(%d, %d) = %d\n", a, n, fn(a, n));
12     printf("s = %d\n", SumA(a, n));
13 
14     return  0 ;
 15  }

. 17  / * your code will be fitted here * / 
18 is  int Fn ( int A, int n-)

 21 is      for ( int I = 0 ; I <n-; I ++ )

32     for (int i = 1; i <= n; i++)
