小问题求助

寒空

我看完视频后输入
#include<stdio.h>
void main()
{
int a=15;
float b=123.1234567;
doublc c=12345678.1234567;
char d='p';
printf("a=%d,%5d,%o,%x\n",a,a,a,a);
printf("b=%f,%If,%5.4If,%e\n,b,b,b,b);
printf("c=%If,%f,%8.4If\n",c,c,c);
printf("d=%c,%8c\n",d,d);
}

但它显示
C:\Program Files\Microsoft Visual Studio\MyProjects\adawdad\adadw.c(5) : warning C4305: 'initializing' : truncation from 'const double ' to 'float '
C:\Program Files\Microsoft Visual Studio\MyProjects\adawdad\adadw.c(6) : error C2065: 'doublc' : undeclared identifier

执行 cl.exe 时出错.

错误有好多
我简单的改了下
自己去对比

#include<stdio.h>
void main()
{
        int a=15;
        float b=123.1234567;
        double c=12345678.1234567;
        char d='p';
        printf("a=%d,%5d,%o,%x\n",a,a,a,a);
        printf("b=%f,%lf,%5.4lf,%e\n",b,b,b,b);
        printf("c=%lf,%f,%8.4lf\n",c,c,c);
        printf("d=%c,%8c\n",d,d);
}

细心细心！！！！！！！！！！

C:\Program Files\Microsoft Visual Studio\MyProjects\adawdad\adadw.c(5) : warning C4305: 'initializing' : truncation from 'const double ' to 'float '
如果是float类型的数，最后要加f

C:\Program Files\Microsoft Visual Studio\MyProjects\adawdad\adadw.c(6) : error C2065: 'doublc' : undeclared identifier
没有doublc 只有double

C:\Program Files\Microsoft Visual Studio\MyProjects\adawdad\adadw.c(6) : error C2146: syntax error : missing ';' before identifier 'c'
double写错了，自然识别不了变量c

其实都是小错~~自己改改看~~细心吧~~编程本身就有细心的~~
支持楼主{:7_155:}加油吖！！！

错的还挺多但都是小错
我改了下

1. #include<stdio.h>
   
2. void main()
   
3. {
   
4.         int a=15;
   
5.         float b=123.1234567;
   
6.         double c=12345678.1234567;
   
7.         char d='p';
   
8.         printf("a=%d,%5d,%o,%x\n",a,a,a,a);
   
9.         printf("b=%f,%lf,%5.4lf,%e\n",b,b,b,b);
   
10.         printf("c=%lf,%f,%8.4lf\n",c,c,c);
    
11.         printf("d=%c,%8c\n",d,d);
    
12. }

话说貌似有人发过了  
(*^__^*) 嘻嘻……

比如 楼主你double 貌似写成了doublc
其他的你自己对吧
不知道楼主找不同好不好
