Teach you step by step how to print an inverted triangle in C language

When you first learn the C language, everyone will come into contact with the compilation triangle. This article describes the compilation code of the inverted triangle. Let’s take a look.

C language code for printing inverted triangles:

#include<stdio.h>
void main()
{ 
int i,j,k,l;//i为第几层星号；k为星号前的空格数；j为星号数；l为打印的行数；
printf("请输入需要打印的行数：\n");
scanf("%d",&l);
printf("打印的图案为：\n");
for(i=1;i<=l;i++)
{
for(k=1;k<=i-1;k++)
printf(" ");//输出空格
for(j=1;j<=2*(l-i)+1;j++)//输出星号；
 /*每层2*l-1为每行的星号数；
每层2*(i-1)为星号前的空格数；
星号数-空格数==所在行星号数；*/
printf("*");
printf("\n");//输出空格，换行输出每行的星号；
}
}/*抓住三点：
1、第几层即i栏；
2、每层的空格数即k栏；
3、每层的星号数即j栏；
     */
