求大神解答：missing ';' before 'constant'
编码时总是出现error C2143: syntax error : missing ';' before 'constant'，不太懂，新手小白，求论坛大神多多指点，谢谢啦！下面是代码：#include<iostream.h> double interpl(int t,double u);
#include<math.h> void main()
#include<stdio.h> {
#include<stdlib.h> int ml=100;

const n=40; double T=100;
const h=1000; double q[8],x0[2*m],x2[2*m];
const 1=L/h+1;（这里总是显示missing ';' before 'constant'，求解答） double array[8];

一个字。乱。好乱。乱七八糟。。。没法看。自己把代码整理后再来问。
