C++ generates a dynamic two-dimensional array through dynamic memory allocation, which needs to multiply rows and columns into even numbers.

# Contains? " stdio.h "

# Contains? & ltstdlib.h & gt

# Contains? "Time. h"

int？ main(int？ argc，char？ *argv[]){

int？ m，n，I，j，**p，* q；

Srand ((unsigned) time (empty));

m = rand()% 10+ 1；

while(m *(n = rand()% 10+ 1)& amp； 1); //Make sure that m*n is an even number.

q=(int？ *)malloc(sizeof(int)* m * n)；

if(q==NULL？ ||? (p=(int？ **)malloc(sizeof(int？ *)*m))==NULL){

Printf ("Application? Memory? Failed ... \ n ");

Return? 0;

}

for(I = 0； I & ltm；; p[I]= q+n * i++)； //organized into a two-dimensional array

for(I = 0； I & ltm；; i++){

for(j = 0； j & ltn； j++)

printf("%2d "，p[I][j]= rand()% 5+ 1)；

printf(" \ n ")；

}

Free (q);

Free (p);

Return? 0;
