C语言数组元素平移函数实现及示例

#include <stdio.h>

void fun(int *w, int p, int n) { int i, j, t; for (i = 0; i <= p; i++) { t = w[i]; for (j = i; j < n - 1; j++) { w[j] = w[j + 1]; } w[n - 1] = t; } }

int main() { int a[12] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}; int i, m; scanf('%d', &m); fun(a, m, 12); for (i = 0; i < 12; i++) printf('%3d', a[i]); printf(' '); return 0; }
