在矩阵a中选出各行最大的元素组成一个一维数组b。

Question

#include
void wwjt();
#define R 3
#define C 4

int * MaxRow(int a[R][C])
{

    int i,j,imax;

/**********Program**********/

？？？？？？？？？？？？这儿怎么补？

/********** End **********/
return b;
}

void main()
{

int a[R][C];
int *b,i,j;
for(i=0;i<R;i++)
for(j=0;j<C;j++)
scanf("%d",&a[i][j]);

b=MaxRow(a);
    for(i=0;i<R;i++)
    {
            printf("%4d",b[i]);
    }
    wwjt();

}

void wwjt()
{

    FILE *IN,*OUT;
    int  a[R][C];
    int  *b,i,j;
    IN=fopen("in.dat","r");
    if(IN==NULL)
    {
            printf("Please Verify The Currernt Dir..It May Be Changed");
    }
    OUT=fopen("out.dat","w");
    if(OUT==NULL)
    {
            printf("Please Verify The Current Dir.. It May Be Changed");
    }
    for(i=0;i<R;i++)
    {
            for(j=0;j<C;j++)
            {
        fscanf(IN,"%d",&a[i][j]);
            }
    } 

b=MaxRow(a);

for(i=0;i<R;i++)
    {
            fprintf(OUT,"%d\n",b[i]);
    } 


    fclose(IN);
    fclose(OUT);

}
