Matrix:
-Multidimensional Array
-Matrix consist of the rows and columns.
Syntax-
array[row][column]
//Matrix with numbers of rows and columns
Example-
Matrix is:
1 2 1
4 3 1
1 1 1
occurrence of 1 is 6
occurrence of 4 is 1
etc
program:
#include< iostream>
int main()
{
int a[10][10],r,c,i,j,count=0,num;
cout<<"Enter rows and columns in matrix"<< endl;
cin>>r>>c;
cout<<"Enter "<< r*c<<" number in matrix"<< endl;
//input in matrix
for(i=0;i< r;i++){
for(j=0;j< c;j++)
{
cin>>a[i][j];
}
}
cout<<"Matrix is "<< endl;
for(i=0;i< r;i++){
for(j=0;j< c;j++)
{
cout<< a[i][j];
}
cout<< endl;
}
cout<<"Enter number to search"<< endl;
cin>>num;
for(i=0;i< r;i++)
{
for(j=0;j< c;j++)
{
if(a[i][j]==num)
count++;
}
}
cout<<"Occurrence of "<< num<<" is "<< count;
}
Enter rows and colums in matrix
3 3
Enter 9 number in matrix
1 2 3 1 4 5 1 6 7
Matrix is
1 2 3
1 4 5
1 6 7
Enter number to search
1
Occurrence of 1 in matrix is 3
