今天一起分析C语言的算法之7画爱心。
算法题目:
用c语言实现一个画爱心函数。
编程思路分析
爱心,是指同情怜悯之心态。
包括相应的一定行动,是一种奉献精神,更是关怀、爱护人的思想感情,包括于所有情感之中。
其深层含义是保护所有的动植物,广义指保护所有生命、包括大自然万物。
画爱心编程思路:
1、先画爱心第一排;
2、用for函数嵌套实现爱心形状,即显示呈递减趋势规律的中间7排;
3、最后一个*与上面的规律脱节了,要用独立的for语句实现显示。
程序范例
#include <stdio.h>
int main()
{
int i,j;
/*前三排的规律性不强,直接显示就好了*/
printf(" ***** *****\n"" ********* *********\n""
************* *************\n");
/*显示中间三排*/
for(i=0;i<3;i++)
{
for(j=0;j<29;j++)
printf("*");
printf("\n");
}
/*显示呈递减趋势规律的中间7排*/
for(i=0;i<7;i++)
{
/*空格个数逐行增加*/
for(j=0;j<2*(i+1)-1;j++)
printf(" ");
for(j=0;j<27-i*4;j++)
printf("*");
printf("\n");
}
/*最后一个*与上面的规律脱节了 所以独立显示*/
for(i=0;i<14;i++)
printf(" ");
printf("*\n");
return 0;
}
程序运行结果案例:
祝各位朋友:
春节快乐;
阖家团圆;
幸福美满。
