#include <stdio.h> void main() { float a[20],min,max; int i; for(i=0;i<20;i++) { printf("Please input the %dth number.",i+1); scanf("%f",&a[i]); } min=a[0]; max=a[0]; for(i=1;i<20;i++) { if(a[i]<min) min=a[i]; else if (a[i]>max) { max=a[i]; } printf("min=%f,max=%f",min,max); } //return 0; }

来自CODE的代码片

20个数中找最大数或最小数

用mingw编译后提示如下错误

 error: '::main' must return 'int'

 void main()

           ^

改正办法是：

将void main（）改为int main（）就行了。原因我没有深究。
