初始化赋值时a = b = 常数 的易犯错误

 1 #include <stdio.h>
 2 #include <stdlib.h>
 3 int main()
 4 {
 5     int a,b; a=b=2; //成功                            
 6     //int a = b = 2;失败
 7     printf("%d %d",a,b);
 8     system("pause");
 9     return 0;
10 }

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int b = 2; //声明并赋予其值                  
    int a = b = 2;
    printf("%d %d",a,b);
    system("pause");
    return 0;
}
