Answer 1

#include <stdio.h>
void Swap1(char *s[3])
{
char tmp[80] = {0};
int i, j;
for (i = 0; i < 2; ++i)
{
for (j = 0; j < 2; ++j)
{
if (strcmp(s[j], s[j+1]) < 0)
{
strcpy(tmp, s[j]);
strcpy(s[j], s[j+1]);
strcpy(s[j+1], tmp);
}
}
}
}

int main(void)
{
char *str[3]={"China","America","France"};
Swap1(s);
for (i = 0; i < 2; ++i) printf("%s\n", s[i]);
return 0;
}
