c语言——用一维数组输出杨辉三角形

一.代码

#include <stdio.h>
int Num[100];
int Hang;
int Lie;
int a;
int Flag;
int main() {Lie = 1;Hang = 1;a = 0;while (1) {//列1为1if (Lie == 1) {Num[1] = 1;Lie++;}//数据存到数组里面while (Hang >= Lie && Hang != 2) {	if (Hang!=Lie) {Flag = Num[Lie] + Num[Lie - 1];//列从2开始}if (a == 1) {Num[Lie-1] = Num[0];a = 0;	}Num[0] = Flag;	a++;Lie++;}//当列大于行让列等于行if (Lie > Hang) {Lie = Hang;if (Lie>2) {//给一排的倒数第二个赋值Num[Lie - 1] = Num[0];}}//行等列为1if (Hang == Lie) {if (Hang % 2 == 0 && Hang > 2) {Num[Lie - 1] = Num[0];}Num[Hang] = 1;}//将这个循环的数组里面的元素全部发送出去for (int i = 1; i <= Hang; i++) {printf("%5d", Num[i]);}printf("\n");a = 0;Lie = 1;Num[0] = 0;Hang++;}
}
