求大神帮我看看这段代码！已自行解决

林爸爸

#include<stdio.h>

int main()
{

        int i;
        char j;
        float k;

        i = 123;
        j = 'C';
        k =3.14;

        printf("size of int is %d\n", sizeof(int));
        printf("size of i is %d\n",sizeof(i));
        printf("size of char is %d\n",sizeof(char));
        printf("size of j is %d\n",sizeof j);
        printf("size of float is %d\n",sizeof(float));
        printf("size of k is %d\n",sizeof k);
        return 0;

}
Ubuntu下运行不了，Windows可以是Ubuntu配置问题还是码错了

warning: format ‘%d’ expects argument of type ‘int’, but argument 2 has type ‘long unsigned int’

很可能是Ubuntu出错
代码没有问题
感觉学c还没有必要在Ubuntu进行

原因找到了！
format ‘%d’ expects argument of type ‘int’, but argument 2 has type ‘long unsigned int
把%d换成%ld完美运行
