C语言程序改错：删除数组中指定元素

/*------------------------------------------------------- 【程序改错】

题目：假定整数数列中的数不重复，并存放在数组中。下列给定程序中函数fun的功 能是：删除数列中值为x的元素。变量n中存放数列中元素的个数。

-------------------------------------------------------*/ #include <stdio.h>

#define N 20

int fun(int *a,int n,int x) { int p=0,i; a[n]=x; while ( x != a[p] ) p = p + 1; /FOUND/ if (p == n) return -1; else { for(i = p; i < n - 1; i++) /FOUND/ a[i] = a[i+1]; return n - 1; } }

main() { int w[N] = {-3,0,1,5,7,99,10,15,30,90}, x, n, i; n = 10; printf('The original data : '); for (i = 0; i < n; i++) printf('%5d',w[i]); printf(' Input x (to delete): '); scanf('%d',&x); printf('Delete : %d ',x); n = fun(w, n, x); if ( n == -1 ) printf('Not be found!

'); else { printf('The data after deleted: '); for (i = 0; i < n; i++) printf('%5d',w[i]); printf('

'); } }
