请编写一个C函数,该函数将一个字符串逆序

#include<stdio.h>
#include<string.h>
#define N 50

void strRev(char *s)
{
char temp;
char *end = s + strlen(s) - 1;
while (end > s)
{
temp = *s;
*s = *end;
*end = temp;
--end;
++s;
}
}

int main()
{
char s
;

printf("Enter string!\n");
fgets(s,N,stdin);

strRev(s);

printf("The strRcv string!");
puts(s);

return 0;
}
