Answer 1

/* 我给你的绝对是 C 语言程序, 连 C++ 的单行注解也没有, 且经过测试. */
#include "stdio.h"
void main(){
char Letter = 'A';
int Row, i, Cnt = 1;
printf("Please input the count of rows: ");
scanf("%d", &Row);
for(; Row > 0; Row--, Cnt += 2, Letter++){
for(i = 40 - Cnt / 2; i > 0 ;i--) printf(" ");
for(i = 1; i <= Cnt; i++) printf("%c", Letter); printf("\n");
}
printf("Press any key to continue...\n");
getchar();
}

/* 运行结果示例: 绝对是你要的等腰三角形状的, 只是百度这里的显示效果有可能变形
Please input the count of rows: 1
                                        A
Press any key to continue...
Please input the count of rows: 2
                                        A
                                       BBB
Press any key to continue...
Please input the count of rows: 3
                                        A
                                       BBB
                                      CCCCC
Press any key to continue...

//---------------------------------------------------------------------------

#include <stdio.h>
#include <assert.h>

int main(void)
{

int i,j,r;
scanf("%d",&r);
assert(r>0&&r<27);
for (i = 1; i<=r; i++) {
for (j=1; j<40-i; j++)
putchar(' ');
for (j=0; j<2*i-1; j++) putchar(64+i);
putchar('\n');
}

return 0;
}
