GGGGGGGGGGGGG用C语言 for 写出来

#include<stdio.h>
main()
{
char a[][7]={
{' ',' ',' ',' ',' ',' ','A'},{' ',' ',' ',' ',' ','B','B','B'},{' ',' ',' ',' ','C','C','C','C','C'},{' ',' ',' ','D','D','D','D','D','D','D'},{' ',' ','E','E','E','E','E','E','E','E','E'},{' ','F','F','F','F','F','F','F','F','F','F','F'},{'G','G','G','G','G','G','G','G','G','G','G','G','G',}
};
int i,j;
for (i=0;i<7;i++)
{for(j=0;j<13;j++)
printf("%c",a[i][j]);
printf("\n");
}
}

LZ，A应该在中间吧，有没搞错题。。。
要是没错也可以编

#include <stdio.h>
main()
{int i,j,k;
char c='A';
for(i=1;i<8;i++)
{for(j=i;j<7;j++)
printf(" ");
for(k=1;k<=(2*i-1);k++)
printf("%c",c);
c++;
printf("\n");
}
}

问下2楼的，如果这个金字塔足够大比如从A到Z，全用PRINTF加空格的输出法，那就太累了

[CODE]

TC调试的，代码不太规范，凑合看吧
#include "stdio.h"

main()
{
int i, j;
for (i=0; i<=6; i++)
{
for (j=1; j<=6-i; j++) printf(" ");
for (j=1; j<=2*i+1; j++) printf("%c", 'A'+i);
printf("\n");
}

getch();
}

[/CODE]

[CODE]
#include <stdio.h>

#define LINES 6

int main()
{
int i, j;
for (i = 0; i <= LINES - 1; i++)
{
for (j = 1; j <= LINES - 1 - i; j++) printf(" ");
for (j = 1; j <= 2 * i + 1; j++) printf("%c", 'A' + i);
printf("\n");
}
return 0;
}

[/CODE]

楼上写的都很好啊
#include "stdio.h"

main()
{
int i, j,j1;
char c;
printf("请输入金字塔的最地层字母:");
scanf("%c",&c);
j1=(int)(c-'a');
for (i=0; i<=j1; i++)
{
for (j=1; j<=6-i; j++) printf(" ");
for (j=1; j<=2*i+1; j++) printf("%c", 'A'+i);
printf("\n");
}

getch();
}
我的机器有问题,没装编译器,帮我改改有没有错的地方.谢谢

恭喜，TC编译成功、运行成功！

LS``拿去DEV-C++调试一下啊````
看看怎么样```
