运行结果:
* *** ***** ******* ***** *** * Press any key to continue
#include<stdio.h> int main() { int i,j,k=3; for(i=1;i<=7;i++) { if(i<=4) { k--; for(j=0;j<=k;j++)printf(" "); for(j=1;j<2*i;j++)printf("*"); printf("\n"); } else { k++; for(j=0;j<=k;j++)printf(" "); for(j=1;j<(3-k)*2;j++)printf("*"); printf("\n"); } } return 0; }
方式二:
#include<stdio.h> int main() { int i,j; for(i=1;i<5;i++) { for(j=1;j<=4-i;j++)printf(" "); for(j=1;j<2*i;j++)printf("*"); printf("\n"); } for(i=3;i>0;i--) { for(j=1;j<=4-i;j++)printf(" "); for(j=1;j<2*i;j++)printf("*"); printf("\n"); } return 0; }
