#include <stdio.h>
    
    
    int main(int argc, char *argv[])
    {
    	char c1[27], c2[27];
    	char high = 0, tmp = 0;
    	int i, k;
    	
    	//创建字母表
    	for(i=0; i<26; i++)
    	{
    		c1[i] = 'a' + i;
    		c2[i] = 'z' - i;
    	}
    	c1[26] = c2[26] = 0;
    		
    	printf("请输入你要的金字塔高度：");
    	scanf("%d", &high);
    	if(high>26)
    	{
    		printf("没那么多英文字母⊙﹏⊙\n");
    		return 0;
    	}
    	
    	for(i=0; i<high; i++)
    	{
    		for(k=0; k<high-i; k++)
    			putchar(' ');
    		
    		tmp = c1[i+1];
    		c1[i+1] = 0;
    		printf("%s", c1);
    		c1[i+1] = tmp;
    		
    		printf("%s\n", c2+26-i);
    	}
    	for(i=high-2; i>=0; i--)
    	{
    		for(k=0; k<high-i; k++)
    			putchar(' ');
    		
    		tmp = c1[i+1];
    		c1[i+1] = 0;
    		printf("%s", c1);
    		c1[i+1] = tmp;
    
    		printf("%s\n", c2+26-i);
    	}
    	return 0;
    }

再优化：

#include <stdio.h>
    #define print(n, m, s)	printf("%"##n##.##m##"s", s);
    
    int main(int argc, char *argv[])
    {
    	char c1[] = "abcdefghigklmnopqrstuvwxyz";//字母表 
    	char c2[] = "zyxwvutsrqponmlkgihgfedcba";//倒序字母表 
    	char high = 0, tmp = 0;
    	int i, k;
    
    	printf("请输入你要的金字塔高度：");
    	scanf("%d", &high);
    	if(high>26)
    	{
    		printf("没那么多英文字母⊙﹏⊙\n");
    		return 0;
    	}
    	
    	for(i=0; i<high; i++)
    	{
    		tmp = c1[i+1];
    		c1[i+1] = 0;
    		printf("%26s", c1);
    		c1[i+1] = tmp;
    		
    		printf("%s\n", c2+26-i);
    	}
    	for(i=high-2; i>=0; i--)
    	{
    		tmp = c1[i+1];
    		c1[i+1] = 0;
    		printf("%26s", c1);
    		c1[i+1] = tmp;
    
    		printf("%s\n", c2+26-i);
    	}
    	return 0;
    }

看这个：

#include <stdio.h>
    #include <stdlib.h>
    
    #define strhigh "19"		//高度 
    
    #define print(x) printf("%"strhigh"."strhigh"s", x);
    
    int main(int argc, char *argv[])
    {
    	char c1[] = "                         abcdefghigklmnopqrstuvwxyz";//25个空格+字母表 
    	char c2[] = "zyxwvutsrqponmlkgihgfedcba";//倒序字母表 
    	int i, k;
    	int high = atoi(strhigh);
    
    	for(i=0; i<high; i++)
    	{
    		print(c1+26-(high-i));
    		printf("%s\n", c2+26-i);
    	}
    	for(i=high-2; i>=0; i--)
    	{
    		print(c1+26-(high-i));
    		printf("%s\n", c2+26-i);
    	}
    
    	return 0;
    }

下面这个，您随便看着办吧：

#include <stdio.h>
    int main(int argc, char *argv[])
    {
    
    char c[][52] = {
    "                         a","\

    };
    
    	int high, i;
    	printf("请输入高度：");
    	scanf("%d", &high);
    
    	for(i=0; i<high; i++)
    		printf("%s\n", c[i]);
    	for(i=52-high; i<51; i++)
    		printf("%s\n", c[i]);
    
    	return 0;
    }

得，寻得赵老师指点，终极版：

#include 
      
       
    #define ab(i) ( (i^(i>>sizeof(i)))-(i>>sizeof(i)) ) //abs()
    char c1[]="abcdefghigklmnopqrstuvwxyz";
    char c2[]="zyxwvutsrqponmlkgihgfedcba";
    int n,i,k;
    int main(int argc, char *argv[])
    {
    	printf("请输入高度：");
    	scanf("%d", &n);
    	n = n % 26;
    
    	for (i=1-n; i<n; i++)
    	{
    		k=n-ab(i);
    		printf("%*.*s",n,k,c1);
    		printf("%s\n",c2+27-k);
    	}
    	return 0;
    }
