我要疯了，高手帮忙来看看，之前一直在用的变量，突然之间就说我没定义过，不给编译了呢
#include <stdio.h>#include <math.h>
int numbera,numberb;
int a,line,i;
int c,d; //line counter use to different lines
int e=2,f=2; //let two line have same value
int counterspace,counternum; // counter the space in result
int numberrow=0;
int numberbasic=10;
int result;
void print_eline1() //+--------------------+
{
if(a!=0) //first bar underline
{
printf("+");
}
for(a=0;a<(2*numbera-1)*d;a++) // space
{
printf(" ");
}
printf("+");
for(a=0;a<2*numbera-1;a++)
{
printf("-");
}
printf("+");
for(a=0;a<19-2*numbera;a++)
{
printf("-");
}
printf("+");
for(a=0;a<2*numbera-1;a++)
{
printf("-");
}
printf("+\n");
}
void print_eline2() //+--------------------+

for(a=0;a<2*numbera-1;a++)
{

}
printf("+");
for(a=0;a<19-2*numbera;a++)
{

for(a=0;a<2*numbera-1;a++)

void print_oline1() //|0 1 2 3 4 5 6 7 8 9|

int main (void)
{

/*

printf("+");
for(a=0;a<19;a++)

printf("+\n");
//result number
printf("|%d",numberrow);
for(a=0;a<=(result+21)/20;a++)
{
printf("|0");
for(i=1;i<numberbasic;i++)

printf("|");
printf("\n");
以上的都是好好的。
我只是想在中间查入一条
if(counterspace==39)
{
counterspace=counterspace+1;
}
gcc的时候就老是说我这行的counterspaced没有定义过。怎么回事啊？请高手指教。
