Question

c++怎么总是提示说error C2181: illegal else without matching if

#include<iostream.h>
#include<stdlib.h>
#include<iomanip.h>
#include<time.h>
void Count(int a[ ] [4], int m, int b[],int c[])
{
int i,j,k=0,t=0;
for(i=0;i<=m-1;i++)
for(j=0;j<=3;j++)
if(a[i][j]%2==0)
b[k]=a[i][j];
k++;
else
c[t]=a[i][j];
t++;
if(!t)
cout<<"d数组数据个数为0！";
if(!k)
cout<<"无偶数！";
}
void main()
{int data[3][4], c[12]={0}, d[12]={0};
int i,j;
srand(unsigned(time));
for(i=0;i<=2;i++)
for(j=0;j<=3;j++){
data[i][j]=rand();
}
Count (data,3, c, d );
for(i=0;i<12;i++)
cout<<setw(8)<<c[i]<<"\t";
for(j=0;j<12;j++)
cout<<setw(8)<<d[j]<<"\t";
}

Answer 1

if后面只能接一个语句，你这里有两个语句b[k]=a[i][j];
k++;

Answer 2

11和12行应该在{}里if(a[i][j]%2==0){
b[k]=a[i][j];
k++;}
else ....你这样就是if(a[i][j]%2==0){
b[k]=a[i][j];}
k++;
else

Answer 3

if(a[i][j]%2==0)
{/*加大括号*/
b[k]=a[i][j];
k++;
}
else
