The ij here said ranks, k said what?




Int * add (int item [])
{
Int I=0, j=0;
Static int the teb [4]={0, 0, 0, 0}, TMP [4]={0, 0, 0, 0};
for(i=0; I & lt; 4. I + +)
{
If (item [I]!=0)//if the Numbers are there in this grid
{
The teb [j++]=item [I];
}
}

for(i=0; I<4. I++)
{
If (teb [I]==teb [I + 1))//if the same two Numbers, the merger
{
The teb [I] *=2;
The teb [I + 1)=0;
Score=score + teb [I];
}
}
J=0;

TMP/j++=teb [I];
}
}
Return (int *) (& amp; TMP);
}

The return here (int *) (& amp; TMP); What's the meaning of, and any other written?

CodePudding user response:

Returns the address of the TMP, other way is to directly define a pointer, pointer to return

CodePudding user response:

TMP saw no definition

CodePudding user response:

 return TMP. 

Is this also can write,
Because the TMP is an array, array name is the first address of the array,

CodePudding user response:

& TMP is dross, TMP is generally regarded as the first address, more like a right value, can also take a address is beyond the wildest dreams,

But I tried the following is not an error,
& TMP is an int (*) [4], a pointer to the 4 times int array length, is my pointy-haired, this type in the past few insights,
Very interesting, however, has certain practical value,

So I have a views: & amp; TMP TMP is not here for the first address, and just as an array of reference
