#Single_Dimensional_Array
The single-dimensional array may be defined as the type of array capable of holding the values of the same data centre in the form of a list
EXAMPLE; SEE BELOW
#include <iostream>
#include <conio.h>
using namespace std;
void main()
{
int val_array[3];
int int_val=1,counter;
cout<<"Please enter three numbers that you want to multiply"<<endl;
for(counter=0;counter<3;counter++)
{
cin>>val_array[counter];
int_val = int_val*val_array[counter];
}
cout<<"The multiplication of these three numbers is = "<<int_val;
getch();
}
#Multidimensional_Array
The multidimensional array may be defined as the array that holds the values in the way a matrix does. The two-dimensional array is used very often, and with the increase in the size of dimension, the array gets complicated.
EXAMPLE; SEE BELOW
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
int val_array[5][5];
int count_rows,count_cols,counter1,counter2;
cout<<"Please enter the size of the rows and columns that you wnant to input: ";
cin>>count_rows>>count_cols;
cout<<"PLease enter the values for matrics in row wise manner"<<endl;
for(counter1=0;counter1<count_rows;counter1++)
for(counter2=0;counter2<count_cols;counter2++)
cin>>val_array[counter1][counter2];
cout<<"The matrix will be as follows"<<endl;
for(counter1=0;counter1<count_rows;counter1++)
{
for(counter2=0;counter2<count_cols;counter2++)
cout<<val_array[counter1][counter2]<<" ";
cout<<endl;
}
getch();
return 0;
