本来是想来个简单的结果看到楼下说要登入这些功能。。。
这是简单的
#include <stdio.h>int main (void)
{
double a=10000
int i
printf ("请输入你要提取的金额:")
scanf ("%d",&i)
printf ("您的账户余额:%g元",a-i)
return 0
}
再来个稍难得吧。。。
#include <stdio.h>int main (void)
{
char mm[6]
double a=10000
int i=0,g
printf ("[1]取款[2]查询余额:")
scanf ("%d",&g)
switch (g)
{
case 1:printf ("请输入提取金额:")scanf ("%d",&i)printf ("账户余额%g",a-i)break
case 2:printf ("账户余额%g",a-i)break
default:printf ("选项错误!\n")break
}
return 0
}
从编译器复制下来的代码中文都要乱码。。。
