利用函数实现较为简单，但是输入的整数大小有一定的限制，这里不能超过10位，超过后因为超过了整形的表示范围，从而不能将其正确的反序，如果想不受表示范围的限制，可以对整数进行分割（利用对10求余和对10进行整除），再逐位的输出。
#include <stdio.h>
void main()
{
int num ;
scanf("%d",&num);
printf("Result = %d\n", 0-num);
}
#include <stdio.h>
void main()
{
int n;
scanf("%d",&n);
while(n)
{printf("%d ",n%10);
n=n/10;
}
}
看在lz这么急的份上 ~
#include <stdio.h>
#include <string.h>
int main()
{
int num;
char s[12];
int i, len;
char t;
printf("input a number : ");
scanf("%d", &num);
sprintf(s, "%d", num);
len = strlen(s);
for(i=0; i < strlen(s)/2; i++)
{
t = s[i];
s[i] = s[len -1 -i];
s[len -1 -i] = t;
}
puts(s);
}
