c语言编程操作如何编写下面这个代码

Question

c语言:编写一函数，使输入的字符串按逆序存放并统计字符串中大写字母的个数，输出字符串和大写字母的个数。

Answer 1

#include <string.h>
void fun(char *p,int n)
{
	char temp;
	for (int i = 0; i < n / 2; i++)
	{
		temp = p[i];
		p[i] = p[n - i - 1];
		p[n - i - 1] = temp;
	}
}
int main()
{
	int i, count = 0;
	char a[100] = { 0 };
	scanf_s("%s", a, 100);
	fun(a, strlen(a));

	for (i = 0; a[i] != '\0'; i++)
	{
		if (a[i] >= 'A' && a[i] <= 'Z')
			count++;
		printf("%c ", a[i]);
	}
	printf("\n大写字母数量:%d", count);
	return 0;
