CPP:
int **p = new int*[3];
// int *看成數(shù)據(jù)類型，
// 再看 int *p = new int[3];
// 相當(dāng)于 int *? (*) p = new int (*)[3];
// 兩邊都加了一個(gè)*
for ( int i = 0; i < 3; i++ )
{
??? p[i] = new int[4];
??? for (int j = 0; j < 4; j++)
??? {
??????? p[i][j] = .....//自己賦值
???? }
????
}
C:
? char **p = (char **)malloc(sizeof(char*) * 3);?
//?對比這個(gè)不難理解char *p = (char *)malloc(sizeof(char*) * 3);
//又是兩邊多了一個(gè)*
? int i = 0;
? for (i = 0;i < 3;i++)
? {
????? p[i] = (char *)malloc(sizeof(char) * 4);???
? }
