输出字符菱形c语言怎么实现

以下是一个用C语言实现输出字符菱形的示例程序：

#include <stdio.h>int main() {    int n, c, k, space = 1;    printf("Enter number of rows: ");    scanf("%d", &n);    space = n - 1;    for (k = 1; k <= n; k++) {        for (c = 1; c <= space; c++)            printf(" ");        space--;        for (c = 1; c <= 2*k-1; c++)            printf("*");        printf("\n");    }    space = 1;    for (k = 1; k <= n - 1; k++) {        for (c = 1; c <= space; c++)            printf(" ");        space++;        for (c = 1 ; c <= 2*(n-k)-1; c++)            printf("*");        printf("\n");    }    return 0;}

该程序会要求用户输入行数，然后输出一个以星号（*）组成的菱形。如果想输出其他字符菱形，只需将 printf("*") 替换为 printf("你想要的字符") 即可。
