Question

 C++ help   Displays the number of times the numbers from 1 through 9 appear in a two-dimensional array                    #include <iostream> #include <cstdlib> #include <ctime> using namespace std;  int main() {         //declare numbers array         int numbers[5][3];         srand(time(0));         // Load the array with random numbers 0-9                for (int i=0; i<5; i++)         {                 for (int j=0; j<3; j++)                 {                         numbers[i][j] = rand()%10;                 }         }         // declare a one-dimensional array to count the numbers and initialize to 0                   // Write nested for loops to traverse the array.  Use the two-dimensional         // array's values as an index into the counting array and add 1 to the indexed element          // Output the results (How many of each number was encountered                  return 0; }       //end of main function 

Explanation / Answer

#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;

int main()
{
//declare numbers array
int numbers[5][3];
srand(time(0));
// Load the array with random numbers 0-9   
for (int i=0; i<5; i++)
{
for (int j=0; j<3; j++)
{
numbers[i][j] = rand()%10;
}
}
   int a[15],x,y,c=0,z=0,s;

// declare a one-dimensional array to count the numbers and initialize to 0

for (int i=0; i<5; i++)
{
for (int j=0; j<3; j++)
{
   s=numbers[i][j];
       for(x=0;x<5;x++)
       {
           for(y=0;y<3;y++)
           {
               if(numbers[x][y]==s)
               {
                   c++;
               }
           }
       }
       a[z]=c;
       c=0;
       z++;
   }
}
  
// Write nested for loops to traverse the array. Use the two-dimensional
// array's values as an index into the counting array and add 1 to the indexed element

// Output the results (How many of each number was encountered
   for(int i=0;i<z;i++)
   {
       cout<<a[i]<<endl;
   }

  
return 0;
} //end of main function
