如何用c语言打印x型的字符图形？急求！！！！

#include

#include

char arr;

void output(int n, char ch){

int count = 0;

int tot = 2*(n-1) + 1;

int i, j;

while(count != tot){

if(ch > 'Z')

ch = 'A';

if(ch == 'A' || ch == 'E' || ch == 'I' || ch == 'O' || ch == 'U'){

ch++;

continue;

}

arr[++count] = ch++;

}

for(i = n; i >= 1; --i){

for(j = 0; j < n-i; ++j)

printf(" ");

if(n-i+1 == tot-n+i){

printf("%c

", arr[n-i+1]);

continue;

}

printf("%c", arr[n-i+1]);

for(j = 0; j < 2*(i-1)-1; ++j)

printf(" ");

printf("%c", arr[tot-n+i]);

printf("

");

}

for(i = 2; i <= n; ++i){

for(j = 0; j < n-i; ++j)

printf(" ");

printf("%c", arr[n-i+1]);

for(j = 0; j < 2*(i-1)-1; ++j)

printf(" ");

printf("%c", arr[tot-n+i]);

printf("

");

}

}

int main(){

int i;

char ch;

scanf("%d %c", &i, &ch);

output(i, ch);

return 0;
