c语言字符串如何实现逆序输出

Answer 1

#include <string.h>
#include <stdio.h>
#define N 81
void fun(char *s)
{ int i,n;
char a[81];
n=strlen(a);
for(i=0;i<n;i++)
a[i]=s[n-1-i];
a[i]='\0';
for(i=0;i<n;i++)
s[i]=a[i];
s[i]='\0';
}

main()
{ char a[N];

printf("Enter a string: ");gets(a);
printf("The original string is: ");puts(a);
fun(a);
printf("\n");
printf("The string after modified: ");
puts(a);
}
