二十五岁时我们都一样愚蠢、多愁善感，喜欢故弄玄虚，可如果不那样的话，五十岁时也就不会如此明智。

数据结构在数组的开头插入
#include <stdio.h> #define MAX 5 void main() { int array[MAX] = {2, 3, 4, 5}; int N = 4; // number of elements in array int i = 0; // loop variable int value = 1; // new data element to be stored in array // print array before insertion printf("Printing array before insertion −\n"); for(i = 0; i < N; i++) { printf("array[%d] = %d \n", i, array[i]); } // now shift rest of the elements downwards for(i = N; i >= 0; i--) { array[i+1] = array[i]; } // add new element at first position array[0] = value; // increase N to reflect number of elements N++; // print to confirm printf("Printing array after insertion −\n"); for(i = 0; i < N; i++) { printf("array[%d] = %d\n", i, array[i]); } }
